Regarding RF connectors, reverse polarity simply means reverse gender. In other words, if a male/plug connector usually houses the contact pin, the reverse polarity version will do the opposite. Contrastingly, if a female/jack connector does not usually house the contact pin, the reverse polarity version will. Common RF connector types which are available in reverse polarity versions are SMA and TNC connectors. Reverse polarity RF connectors were designed in response to FCC regulation to deter average consumers from modifying antenna systems to produce a higher gain than FCC regulations allowed.
Regarding RF connectors, the term "bulkhead" simply implies the connetor is designed to mount through a panel. Bulkhead RF connectors usually are designed with a longer thread barrel length and include a washer and hex nut for panel mounting. Different types of bulkhead mounting include rear mount, front mount and thru hole mount
Most factory installed laptop WIFI adapter cards have IPX mating receptacles mounted for antenna lead connections. Hirose U.FL connectors are a direct cross to IPX connectors, which RFmall offers. Usually internal WIFI cards will have two IPX receptacles, one for a main and another for an auxillary antenna connection.
All RF pigtails offered on RFmall.com are in standard lengths. If you need a custom length RF pigtail, visit the RFmall cable wizard to design a custom cable and send in for a quotation. Most quotations will be provided to you within 48 hours.
IPX connectors can be terminated to three different coax cable types, 1.13mm micro coax, 1.32mm double shielded micro coax, and RG 178. 1.32mm double shielded micro coax will give the best performance of the three.
RF coax cable differs in many ways, however the most important point to consider when choosing an RF cable for your application is known as attenuation or cable loss. Thicker diameter cables provide the least amount of attenuation for longer assemblies, however are not as flexible as thinner cables. Smaller RF connectors such as MMCX and SSMB connectors perform better with thinner cable. Each cable choice is application specific. Visit the RFmall RF cable guide for cable specifications
All of the cables offered through RFmall are manufactured to spec. Please allow 1-2 weeks for delivery.
