I've tried running ham diplexers on 2m/440 repeater setups, and if you keep the TX power on each band low, you MIGHT be OK - they aren't designed for 100w CONTINUOUS TX, and they'll melt after some long-winded nets. As it has been stated here plenty of times, you get what you pay for. Use the commercial version - I have - it's well worth the bucks. - Adam - Yahoo!

Re: [Repeater-Builder] Homebrew a 2M/440 crossband coupler?
Derek, Take a look at this one. You can build your own and by choosing components you can can handle all the power you want: http://home.datacomm.ch/hb9abx/duplexer.html and for hf-6/2/70cm: http://home.datacomm.ch/hb9abx/diplhf6m-vuhf.html The weak link will be the capacitors and you can build it with small air variables or your choice of better components. The components in this home brew one are about the same you'll find in most amateur grade diplexers these days. As for amateur grade diplexers, I've had good results with the Comet 2/70cm unit with SO-239 connectors on my 2 meter and 70 cm repeaters. I also had a problem with the units that had pigtails... stay away from them. 73, Tony W4ZT derek_mcintyre wrote: Hello Group, Does anyone have, or know where I can get plans to homebrew a 144/440 MHz crossband coupler (aka diplexer) ??

And they have lots of duplex noise, even on 440 :) I changed all the cabling on mine to RG 393 (142, 214 would work too). Duplex noise gone after that!

Re: [Repeater-Builder] Homebrew a 2M/440 crossband coupler?
I guess that could be a problem, but I've had pretty good luck with mine. If they are kept in a controlled environment so the coax doesn't pull in water, they should be OK. If you're really concerned about it, you can go with a pigtailless model.

RE: [Repeater-Builder] Homebrew a 2M/440 crossband coupler?
I just installed one of the duplexers on my repeater for 2 meters and 440, no problems as of yet, coverage is the same. This is one with the pigtails.
