Antenna Similar to Alien’s ALR8696-C

Posted by Michael Crudele on

Recently a client approached us about the Alien part # ALR8696-C. They were developing new software and need an antenna that utilized LHCP (left-hand circular polarization), which part # ALR8696-C does not. In response, I have come up with two suggestions, both of which come in LH and RH circular polarizations.   Suggestion 1 RCPL-902-09-SNF: This antenna measures in at 10 x 10 inches and features a gain of 9 dBic, a fixed N-Female connector, and an IP rating of 67.   Suggestion 2 RCPL-902-8-RTM-8: This antenna is the industry standard for passive UHF VHF RFID installations. It measures in...

How to identify Coaxial Connector Types

Posted by Michael Crudele on

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...
