How to identify Coaxial Connector Types

October 14, 2017 10:10:41 PM EDT

Over the years, we've had many customers come to us looking to clarify RF connector types when they are specifying and purchasing RF coaxial cable assemblies.  There are many different types of connectors out there, including Type-N, UHF (aka PL-259 / SO-239) TNC, RPTNC, BNC, SMA & RPSMA.

Most people can tell the difference between the "standard" connector types, but many people, ourselves included, find it difficult to identify the gender of reverse polarity connectors? Here we will do our best to help you identify the difference between male and female connectors in terms of their polarity—standard or reverse (RP). 

Standard Polarity Coaxial Connectors.

When trying to identify male and female connectors keep in mind the following:

  • When mating a plug and a jack, it is important to ensure that both connectors have the same polarity. For example, the plug and jack should both be standard polarity, or both must be reverse polarity. 
  • Typically, standard RF plugs are male, and the threads are on the inside of the shell.
  • Typically, standard RF jacks are female, and the threads are on the outside of the shell.
  • The shell of a plug (male) typically covers the shell of a jack (female).

Examples - standard polarity

  • A standard polarity female jack has a socket in the middle designed to receive the pin from the male plug, and the jack’s shell has threads on the outside. Here we have shown an SMA jack, typically found on devices such as a 3G/4G/LTE cellular gateway or a GPS receiver.  

female jack

  • A standard polarity male plug has a center pin that sticks out from the middle, and the plug’s shell has threads on the inside. Here we have shown an SMA plug, typically found on the end of a coaxial cable that connects to products such as a 3G/4G/LTE cellular gateway or a GPS receiver.

Examples - REVERSE polarity

  • A "reverse polarity" female jack has a center pin that sticks out from the middle, and the jack’s shell has threads on the outside. Shown here is a RPSMA-Female jack, typically found on such products as a 900 MHz ISM modem, 2.4/5 GHz 802.11 WiFI / WLAN radios or access points.

reverse polarity female jack

  • A "reverse polarity" male plug has a socket in the middle designed to receive the pin from the female connector, and the plug’s shell has threads on the inside. Here we have shown an RPSMA-Male plug, typically found on the end of a coaxial cable that connects to products such as a 900 MHz ISM modem, 2.4/5 GHz 802.11 WiFI / WLAN radios or access points.

    reverse polarity male plug

Remember:

  • standard polarity jack (female) has a socket, whereas a reverse polarity jack (female) has a pin.
  • standard polarity plug (male) has a pin, whereas a reverse polarity plug (male) has a socket.

Connector Types and Genders

The following table identifies for you the various types of connectors commonly used, and their genders:

Connector Type Male (Plug) Female (Jack)

Standard

Type N

 

Type N male plug connector

(Std. N-Male) pin with threads inside

Type N female jack connector

(Std. N-Female) socket with threads outside

UHF (PL259)

UHF (PL259) male plug connector

(UHF Male: PL-259) pin with threads inside

UHF (PL259) female jack connector

(UHF Female: SO-239) socket with threads outside

Standard

TNC

TNC male plug connector

(Std. TNC-Male) pin with threads inside

TNC female jack connector

(Std. TNC-Female) socket with threads outside

Reverse Polarity TNC

(RPTNC)

RPTNC male plug connector

(RPTNC-Male) socket with threads inside

RPTNC female jack connector

(RPTNC-Female) pin with threads outside

BNC

BNC male plug connector

(BNC-Male) pin with threads inside

BNC female jack connector

(BNC-Female) socket with threads outside

Standard SMA

SMA male plug connector

(SMA-Male) pin with threads inside

SMA female jack connector

(SMA-Female) socket with threads outside

Reverse Polarity SMA

(RPSMA)

RPSMA male plug connector

(RPSMA-Male) socket with threads inside

RPSMA female jack connector

(RPSMA-Female) pin with threads outside

 

I hope the descriptions and images have helped you understand the differences between the connector type, polarity, and gender.

Keep in mind that there are also "Reverse-Thread" and "Reverse-Polarity / Reverse-Thread" Connectors, but that's a discusson for another day!!!!!!

UHF, PL-259, SO-239. What is the difference?

October 14, 2017 11:05:07 AM EDT

I get many inquiries each month from customers looking for NMO cable kits and mounts for radios with UHF connectors.  The problem is that there is often confusion concerning the terminology used to describe UHF connectors. The most common questions that I get on this topic are:

  • Is PL-259 the same as UHF Male?
  • Is SO-239 the same as UHF Female?

So, I thought that our blog would be a good place to clear up any confusion once and for all!

Here are the facts...

  • UHF-Male (or UHF Plug) is THE SAME as PL-259.  
  • UHF-Female (or UHF-Jack) is THE SAME as SO-239.

The above connectors are used in applications like amateur / HAM radio, CB / Citizens Band radio, Marine radio & VHF radio.  Typically, the SO-239 (UHF Female/UHF Jack) is installed ON THE RADIO, and the PL-259 (UHF Male/UHF Plug) is installed ON THE CABLE.  The two "mate" and are collectively known as a UHF Connection. 

UHF Male PL-259 vs. UHF Female SO-239

Times-7 A8060 slimline doorway antenna

December 22, 2016 4:41:58 PM EST

Today, a customer came in asking if the Times-7 UHF RFID antenna, part # A8060 was suitable for both FCC & ETSI use.  The answer is that there are typically TWO different models for each and every RFID antenna, one for FCC and one for ETSI.  The only exception is when an antenna is designed as a “wide-band” model that would cover both FCC & ETSI.  In the case of the Times-7 model A8060, there are two different antenna models:

This anenna is super small, and suitable for use in doorways.  It measures in at only 3 inches wide x 25 inches long.  The only drawback is that it is linearly polarized (vs. circular) so it may not work well in applications where RFID tag orientation is not consistent.  If any of our readers has any questions on this, or any other RFID antenna, simply email me at: sales@arcadianinc.com

Recently, there was some confusion regarding the all new B6031 antennas introduced by Times-7. These are the next evolution of the A6031 series of FCC and ETSI 11x8.5 inch, circularly polarized panel antennas for 865 and 915 MHz UHF RFID.

I wanted to take a moment to explain what happened with these part #’s. Times-7 had a typo on their original datasheet, and did not know it (and neither did we.) That has since been corrected by Times-7, and by Arcadian Inc. over the past 48 hours.

The correct information is below, and this is now reflected on both the T7 and arcantenna.com websites. Please ensure that your records have been updated as well.

• B6031-71827 is the 902-928 MHz *FCC* version of the antenna.  LINK HERE for FCC.

• B6031-71828 is the 865-867 MHz *ETSI* version of the antenna.  LINK HERE for ETSI.

The corrected datasheet can be found on the above web links.

My apologies for the confusion,

Mike

An RFID system integrator came in this afternoon complaining that after Intermec discontinued antenna part # 1309-57-0087, they had no equivalent high-gain RFID antennas to offer their clients.  

The 1309-57-0087 antenna has the following specifications: 

  • Size: 14.6 x 14.6 inches & 4.4 Lbs.
  • Frequency Range: 902-928 MHz (UHF, FCC, RFID)
  • Gain: 10 dBic
  • Polarity: RHCP/right hand circularly
  • Rating: IP67 - outdoor rated
  • Beamwidth: 60 x 45 degrees at 3 dB

Here is what we suggested (below) If you are in the same situation, these are models that you should consider: 

A6034: (12x30 inches) http://www.arcantenna.com/a6034-70809-30x12-inch-circularly-polarized-slimline-rfid-antenna-fcc.html

A6034 SlimLine Antenna  SlimLine-A6034S

A6034S: (15x15 inches) http://www.arcantenna.com/a6034s-71003-15x15-inch-circularly-polarized-slimline-rfid-antenna-fcc.html

These models offer 9 dBic of gain (vs. 10 dBic)  but they do have very good propagation, and typically are your best choice to replace the Intermec models.

Zebra AN480 RFID Antenna Mounting Options

April 5, 2016 11:48:58 AM EDT

I had a customer contact me this morning, very frustrated that he could not find a way to mount the Motorola / Zebra AN480 antennas he had purchased for his RFID project.  I told him that the AN480 antennas from Zebra have a customize mounting bolt pattern, specifically so you can’t buy mounts anywhere else – BUT they never came out with any decent mounts.  So, here is what I recommended to him, and to you... 

 

Purchase RFMAX part # S9028PCx96RTN (same exact antenna, IP54 rated, but with pre-attached 8 foot/96 inch cable & RPTNC connector) http://www.arcantenna.com/s9028pcl96rtn-s9028pcr96rtn-10x10-inch-ip54-rated-circularly-polarized-rfid-antenna-with-4-mounting-studs-fcc.html

 

Or, purchase RFMAX part # PAx90209H-FNF (same antenna, IP67 rated, with fixed N-Female connector) http://www.arcantenna.com/pal90209h-fnf-par90209h-fnf10x10-inch-ip-67-rated-circularly-polarized-antenna-fcc.html

 

These two antennas can utilize the HEAVY DUTY mount, which locks firmly in place, RFMAX part # HDMNT: http://www.arcantenna.com/hdmnt-heavy-duty-aluminum-mounting-bracket-wall-or-mast-mount.html

 

Or, they can utilize our fully articulating, easy to install EZM6 mount: http://www.arcantenna.com/fully-articulating-die-cast-wall-or-mast-mounting-kit-for-2-or-4-stud-panel-antennas.html

 

  EZ-M6 Wall/Mast/Pole Combo Mount Heavy Duty Mounting Bracket

 

 

Take a look, and let me know if you have any questions.  I’d be happy to help.  Also, log into our website, and set up an account.  Let me know when you’ve done so, and I’ll set you up with your ddiscounted pricing so you can shop right on the website.

 

Best Regards,

Do I have to use opposing polarity RFID antennas?

October 28, 2015 11:49:04 AM EDT

RFMAX S9028PC

Today, we had a client contact us because they had an installation of RFMAX S9028PCx96RTN circularly polarized RFID antennas that was suffering from poor performance.  The use case was a portal set up in a hallway to track employees coming and going from a job site.  The RFMAX 8.5 dBic, 10x10 inch,  circular polarized RFID panel antennas were set up on both sides of the portal (which was about 4 foot wide) and the antennas were arranged such that they were DIRECTLY opposite on another.

 

Apparently, each time they turned on the Impinj R420 RFID reader, and activated the antenna ports, they were having major trouble reading RFID tags.  However, when they de-activated all of the antennas on one side of the portal, they experienced INCREASED performance, thus leading us to belive that the antennas from one side of the portal were interfering with those on the opposing side.  After investigating, we discovered that all of the circular polarized RFMAX antennas they were using were of the same polarity, in this case LHCP.

 

For maximum performance, RFID antennas should not be positioned directly across from each other.  They should always be off-set from one another, if at all possible.  In addition, when antennas MUST be positioned directly across from each other, in close proximity (< 12-15 feet apart) that is the only time that opposing polarities SHOULD be used.  In this use case, it is quite possible that the antennas are interfering with one another and cancelling out signal.  So, there are two possible corrective actions:

1. Remove all of the antennas from one side of the portal and replace with antennas of opposing polarity, in this case RHCP antennas.

2. Without swapping out the antennas, they can try simply changing the articulation of each set of antennas, if the mounting hardware allows this.  For these 10x10 inch antennas, I'd recommend using the fully articularing RFMAX EZ-M6 antenna mounts.

 

To clarify, what I mean is this…take all of the antennas on the left side of the portal and articulate / position them at a slight angle towards the outside door.  Next, take all of the antennas on the right side of the portal and articulate / position them at a slight angle away from the outside door.  By not having the antennas facing each other directly, they should be able to eliminate a significant amount of the interference.

 

If you have an RFID or other antenna related question, please call us at 1-888-925-5967 or contact us here.
