Re: [Repeater-Builder] Homebrew a 2M/440 crossband coupler?

"Knock on wood,"  after I rebuilt my comet diplexers with RG142 (and 393 on the other one), they hold up to 160 watts continous output from my 440 machine (the 2 meter side is used as receive only).  I have one very long winded net every week, and a couple shorter ones on the system. James

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: and for hf-6/2/70cm: The weak link will be the capacitors and you can

Mine had pigtails, that japanese crap sucks (foil/braid shield). RG 393 was a blessing! James Ken Arck wrote: >At 02:55 PM 2/1/2005 -0500, you wrote: > > 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 n

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. Bob NO6B At 2/1/2005 11:55 AM, you wrote: >A

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! James Ken Arck wrote: At 03:13 PM 2/1/2005 -, you wrote: Does anyone have, or know where I can get plans to homebrew a

Hello Group, Does anyone have, or know where I can get plans to homebrew a 144/440 MHz crossband coupler (aka "diplexer") ?? I would like to find something with wideband characteristics (ie, low pass, high pass) such as some of the diamond or comet models, but needs to be able to handle 100
