Mainly because the BNC connectors seem flimsy in my opinion (I've
had two break on two separate HT's over the past few years) and from
reading up whats posted on the net everyone seems to agree that
steering clear of PL-259 and BNC connectors in repeaters is a good idea.

You want to steer away from junk connectors, and there are a lot of them out
there. BNC's get used with excellent results on all kinds of commercial
applications. Use quality, name-brand connectors. Hamfest specials are
usually cheap overseas junk.

I agree. 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.
You get what you pay for.

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.

RG-214? BNCs work quite nicely with it.

Alex,
I have had over 30 of these repeaters in use and never ran into a problem using
the BNC. I would leave well enough alone if it were me. If you do this you wont
take care of the issue you may be thinking your going to fix by doing so.

Why..? It's a horrible idea and a real potential for trouble.
Would there be some major advantage (we seem to be overlooking)
over the factory installed rx BNC connector?

Mike, the BNC connector was designed for quick
insertion / disconnect and works very well in most applications.
However the Type N connector is much more robust and
would be my choice for critical connections such as a
Duplexer or an Antenna etc

Find out what gear they are using. Make sure it's FCC certified. If you have
a spectrum analyzer, or have access to one, have them fire up the gear and
make sure it doesn't have any spurious spikes within the 440 and 2m ham
band.

And scratch out the chance of ever making friends with any other amateur in
the area that has deployed, or is thinking of deploying, a 902 MHz ham

country almost unusable...

The rule of thumb we used on the military aircraft RF cabling was that when we
were using a larger sized cable like RG-214 we always used a type N, while if
we were using a smaller cable like RG-142 we used a BNC. I worked on
reconnaissance aircraft for the Air Force and Navy. For video

An ISP installed some Motorola Canopy equipment with the antennas
about 20 ft. horizontally from our 2M receive antenna. The noise
floor went up at least 10db. In this case, I had the option of moving
our antenna so it is now about 80 ft. horizontally away. No noise at
all from their equipment
