BNC's leak if using el-cheapo connectors... Most receiver multicouplers use BNC connectors... The new MOTOTRBO repeaters use a BNC on the receiver port and an N connector on the transmitter side... For the duplexers with N connectors, we simply put a male BNC on the radio side and a male N on the duplexer side of the cable. 73s, AJ, K6LOR On Wed, Jan 21, 2009 at 10:21 AM, Chuck Kelsey wrote: > You want to steer away from junk connectors, and there are a lot of them > out > there.

Not a concern for receivers. RG-214? BNCs work quite nicely with it.

Re: [Repeater-Builder] Re: Coax Interconnect (Inside Repeater)
Hi Chuck and the group -- Thanks for this input -- It has been well known for years that the cheapy connectors that most hams purchase won't cut it on repeaters. There are only a couple of manufacturers that I will purchase or that we will purchase in the shop. AMPHENOL silver plated/teflon being one type. As the BNC connectors, well there is many schools of thought about this but good connectors work fine. Heck TX/RX uses them all the time without issue on their duplexers. I also question why we keep hammering on UHF when, we use good connectors, they are still getting a bad rap? UHF has strength and as long as they are treated well they serve well. Where "N" connectors shine is in wet environments, and where constant impedance is a must. As to coax, RG-8 (214, 213) is not a requirement, use teflon RG-142B or RG-223! Both are very good candidates for repeater and duplexer use. Constant impedance, low loss, good/excellent shield - less leakage (or crosstalk), and easy to work with. Certainly, a plus.

I like Amphenol, Kings and RF Industries. Same problem with coax. If you go with something not Mil-Spec (with an actual Mil-Spec number), good luck. Again, there's lots of junk out there.

In my military days, we used a lot of BNC connectors into the 400 MHz range with no problems. Stick with Amphenol or a another good mil-spec brand and you'll be fine.
