[Repeater-Builder] 75 to 50 ohm match

I believe one can match using a length of 62.5 ohm coax, but how long and where to get it? ---You don't use 62.5 ohm coax. You build a transformer (1/4 wavelength or odd multiple of a 1/4 wavelength) out of conventional coax. Electical 1/4 wavelength of course, not physical :-) On the other hand, some would argue the mismatch between 50 ohms and 75 ohms is hardly worth the effort and would simply return their duplexer to match the different common port impedance.

[Repeater-Builder] RCA TACTEC for repeater ?
Hi All, In my yearly "it's too cold to go outside, so I'll cleanup my shack" , I discovered that I have a pair of working RCA TACTEC radios, re-crystaled and re-tuned for 6 meters.Does anyonethink they would be worthwhile to try and make a 6 meter repeater out of ?

[Repeater-Builder] Re: 75 to 50 ohm match
As Ken mentions, you would probably consider sections of quality 50 ohm cable. Going a little more down the road, one would probably cancel the resultant reactance with a variable capacitor. The network would be band specific. Ham Radio Magazine had a nice writeup with the theory some years back. I might be able to make that information avaiable or at least provide the reference information. cheers skipp025 atyahoo.com k9bf [EMAIL PROTECTED] wrote: I have a repeater attached to 300 feet of 75 ohm CATV hard line.

[Repeater-Builder] db420 alternatives?
Ok guys, I waited too long to be able to buy a DB420 for the ham bands, now I need one. We've been using Diamond antennas, but they keep breaking in the wind. So, I need something else. Since I now have the $$ to buy a new antenna, but can't get a DB420 (my first choice for repeater antennas) I need recommendations for a suitable substitute with like characteristics for the 420.

[Repeater-Builder] Re: 75 to 50 ohm match
I have been using catv hard line for 10 years and when i first used it i made some matching transformers from copper pipe and compared it to the line with out and didnt see aney differance swr or power or how well the rx worked i still use it have several runns of differant lengts and sizes and it works great never a problem but i might just be luckey A old ham told me if you never tell a transmiter its 75 ohm cable it will never know the differance . so i never told my radios what i had hooked up to em like the one guy said the mis match isnt that bad for me the only chalange is the connecters good luck AG4ZQ Yahoo!
