Hi Everyone, Yes, this is off-topic a bit, but I know there are some of you here who will be able to get me going in the right direction.
I have a PixelSatRadio RF Pro 1A receive-only moebius loop antenna. It is being used with a Kenwood TS-440S that does not have the provisions for a receive antenna like the K3 does. In order to make sure one doesn't fry the antenna's pre-amp, I need a fool-proof way to ensure that no one ever accidentally sends RF down the coax to that antenna. I have thought about maybe some kind of a PTT enabled antenna switch. I have thought about some kind black box with a circuit one could build that would act as a gatekeeper to allow RF in from the antenna but block any going out. I have searched the 'net and have not yet found anything along those lines that I could implement. So my question to you is, can anyone here recommend such a switch or such a black box circuit? Or maybe propose something else that I'm not even thinking of? Any ideas, suggestions, recommendations? I need this to be on-the-cheap and I'm not opposed to homebrewing something here, though I only have modest-at-best skills in homebrewing. Many many thanks, Dave, AH6TD I now return this reflector to normal programming, already in progress. ;-) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
