My IP67 antenna has water in it, why?

January 22, 2019 6:17:15 PM EST

Recently, a customer complained that an IP67 panel antenna (in this case for RFID) that he purchased at our website had taken on water, he asked if this is acceptable.  Well,  I do have an issue with an IP67 antenna taking on water, technically it should not happen, but... 

The way IP67 is defined is that IP stands for “ingress protection” and the first digit denotes solid particle protection (dust) and the “6” rating means that the ingress of dust is not entirely prevented, but it won’t enter in sufficient quantities to interfere with the operation of the antenna. 

The second digit “7”  is for liquid ingress protection (water) and a 7 rating should allow the antenna to be immersed in up to 1 meter of water for 30 minutes without taking on enough water to affect performance.

The antenna in question is clearly not meeting the IP67 rating.  However, these ratings are tested in a controlled environment and done just one time.  Which means that when temperatures fluctuate and materials expand and contract, and devices (in this case antennas) are in the field for years, or even just days, the rating can be lost. 

The reality is that I’ve not seen ANY antenna that truly lives up to the IP67 rating when it must face direct and often prolonged exposure to rain on the backplane, which was the case here. 

My suggestion in these cases is to purchase antennas with "weep holes" or "drop holes" or to simply drill the holes (at least two) yourself in the plastic antenna radome on the side that faces the ground.  The water is going to get in anyway, but these holes will allow it to drain out and dry quickly.  This is what is typically done in RFID tolling applications when the RFID antennas are placed with the backplane facing the sky (think EZ Pass, Sun Pass, Toll Pass, etc.)

Any other questions??? Write me at

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) /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) /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: /hdmnt-heavy-duty-aluminum-mounting-bracket-wall-or-mast-mount.html


Or, they can utilize our fully articulating, easy to install EZM6 mount: /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,

RFID Journal Live! 2015 Show Recap

Arcadian Launches RFMAX Brand at RFID Live! 2015


It's been several weeks now since the RFID Journal Live! Tradeshow in San Diego, and now that we've managed to catch our breath (at least a little), we can offer a few reflections on 2015's premiere RFID event.


To begin with, show attendance was at it's highest level since 2008, and the increase in traffic from the past few years was noticeable. A good sign that business is continuing to recover, and that the RFID space continues to grow. While many attendees were RFID industry insiders and familiar faces, a significant proportion were also end users from virtually every industry imaginable. More good news for the RFID space as a whole, and for growing RFID adoption in general.


As for Arcadian, we utilized this years show to launch our new brand of RFID products from RFMAX. Key products shown included RFMAX Passive RFID Antennas and Antenna Cables; RFID Weatherproof Reader Enclosures, and the RFMAX Power Mapper.Traffic to the booth was steady for all 3 days of the event, with plenty of people taking notice of the new RFMAX product line. Interest in antennas and weatherproof enclosures was fantastic, but the RFMAX Power Mapper literally stole the show... in fact, we sold out our entire stock of Power Mappers while we were there! (not to worry if you didn't get yours yet... we've since replenished our stock and have more on the way).


Overall, we see interest in RFID applications and products continuing to bloom, and  are thrilled with the response we received for our new RFMAX line. A great show this year all the way around. Our sincere thanks to all of our customers, partners and friends, along with the RFID Journal staff for making this year's RFID Journal Live show one for the books!

We just received results from independent testing of the RFMAX Power Mapper, and the results confirmed exactly what we've been hearing from our customers: The RFMAX RFID Power Mapper does what it says it will, and is an indispensible tool for setting up and troubleshooting any RFID installation. 


According to the report: "This instrument should be a standard part of any RFID installer’s tool box".


A copy of the review is available here:

Can't find Motorola AN400 bistatic RFID antenna? Try our circularly polarized 10x20 inch dual port RFID panel antenna.

Recently, we had an RFID antenna customer come in looking for a Motorola / Zebra RFID panel antenna, model # AN400.  Apparently, the customer was having a difficult time procuring this antenna model for their RFID portals.  We informed them that it was our understanding that the AN400 antenna had been discontinued and/or is generally unavailable from Motorola and the replacement antenna is the updated model  - which carries part # AN440. Both antennas have similar mechanical and RF electrical specifications.


Here are the specs on the AN440 dual element bi-static dual port RFID antena.  This model has two antenna radiators under the radome, one is LHCP, the second is RHCP.


Size: L: 22.6 x W: 10.2 x D: 1.32 inches (575 x 259 x 34 mm)
Weight: 4.2 Lbs. (1.9 kg)
Frequency: 902-928 Mhz for UHF RFID in the FCC band (US, Canada, Mexico, S. America, etc.)
Gain: 9 dBic.  VSWR: 1.4:1.  Axial Ratio: 1 db
Polarity: Left & Right Hand Cirucularly Polarized
Beamwidth, H&V: 70 degrees in both planes
Includes (2) type N-Female fixed connectors on the rear of the unit.
Mounting: 4 1/4-20 threaded studs on the rear of the unit.


You can find futher specifications on this antenna or purchase the equivalent here for part # PRL90209.

This question has come up several times, and I would like to address it in detail.  See my notes below on each of the EZ mounts and what their maximum weight loads are.  Keep in mind that there are TWO ratings for each mount.


A “static” rating, for antennas that will be mounted in a secure location and not be subjected to any vibration at all.

A “subject to vibration” rating, for antennas that will be mounted in a location that is subject to ANY shake or vibration.  That could be the obvious, like on a vehicle, or the less obvious, like next to a stamping machine, or next to a loading dock.

Here is my input:


We are no longer recommending the EZP4 in 2015.  With the popularity of the EZM6 (6 inch die cast aluminum RFID antenna mounting bracket) most customers are leaning towards spending a few extra dollars for this model, and we are spending more and more of our inventory dollars on stocking the EZM6 (wall, mast & combo)


EZM6: 5 lbs. (static install) or 2 lbs. (if subject to vibration)  Suitable for:

·        Laird 10x10” models (S9028PC, PAL902909, PAR90209)

·        MTI 12x12” models (MT-262006)

·        Times-7 smaller models (A6031, A6032)


EZM9: 10 lbs. (static install) or 5 lbs. (if subject to vibration)  Suitable for:

·        Laird 10x10” models (S9028PC, PAL902909, PAR90209)

·        Laird 10x20” model (PRL90209)

·        MTI 12x12” models (MT-262006)

·        Times-7 smaller models (A6031, A6032)

·        Times-7 larger models (A6034 & A6034S) *with or without the sheet metal mounting plate* 


If you are using the EZ mounts in conjuction with Times 7 antenna #'s, A6031, A6032, A6034 or A6034S, you will also require a Times 7 mounting plates.

We at Arcadian Inc. are in the business of selling RFID antennas, and over the years we have sold MANY of the Times-7 A5530 rugged RFID mat antennas, and it's sister - the Race Timing Antenna System (RTAS).  This model is a high-gain (10 dBiL) linearly polarized RFID antenna embedded in a blue, molded polyurethne "mat."  It has come to be the preferred choice of RFID antenna for our clients building chip timing, or RFID race timing systems. 

Why?  Becuase it is simply the fastest and easiest to deploy on race day.  In addition, we also have many clients who use these mats in conjuction with RFID systems used to track event or trade show attendees.  Well known to be extremely durable, with customer deployments growing rapidly since its debut in 2007, the Times-7’s A5530 / RTAS is a proven endurance performer. 

However, we have had MANY clients ask us..."can this antenna survive foot traffic, bike traffic, car traffic?  What about fire trucks, ambulances and 18 wheel tractor-trailor trucks running over the antennas?"

Well, until this year, Times-7 hadn’t attempted to measure and document the weight bearing characteristics of this RFID mat antenna.  So, recently they set out to do exactly that using an external specialist with equipment to validate what customers were already telling us...namely that this antenna can survive just about anything!

**Click Photo for RFID mat antenna datasheet**

Working with a techinical university in their home country of New Zealand, the research team used a hydraulic press to emulate vehicle load.  The Times-7 ultra-low profile ground mat RFID antenna was compressed with a 10,000 lb. point load. The A5530 / RTAS mat withstood more than 600psi. By contrast, the maximum contact surface pressure of a 42,000 lb tandem axle garbage truck is 215psi.

In conclusion, I am happy to report that we can now say with confidence that the weight bearing properties for the A5530 / RTAS RFID ground mat antenna are in excess of any typical heavy commercial vehicle.

For information on using this antenna for your RFID race timing, or chip timing system, or in your trade show or event tracking system, please contact me or a member of the Arcadian Inc. team for assistance.  We are the antenna experts, and we are happy to help!

I wanted to take a moment to inform our RFID clients about a GREAT tool that many RFID professionals feel is an essential part of their "toolkit" in the field:

The RFID Power Mapper from RFMAX is a small (2 1/4 x 2 3/4 inches) hand-held unit that measures relative antennastregth for both linear and circular RFID antennas in the FCC: 902-928 mhz & ETSI: 865-868 mhz ranges.

The unit does NOT require batteries, so it's always ready when you need it.  It simply uses radiated RF power like an RFID tag, and displays signal strength on a simple to read analog guage.  I find it most helpful when comparing one antenna vs. another's gain and beam width in a particular installation, or simpy to test whether we are getting signal from a particular antenna node.

This simple tool can save the professional RFID system integrator a tremendous about of time on the job.  Click the photo below for our product page which will give you a complete overview of the device, and the option to order from our STOCK.
