Big one!!! :-) I thought I had cleared it up. Don't read what I said
understand what I mean. I mispoke myself big time in the first statement. I
really was trying to say it doesn't matter and people don't normally check
the impeadance of a antenna for receiveng.

Yeah, that's what i was trying to say! :-)

Look again at what you wrote above ....

Then look just above at what you wrote in same message ... a contradiction.

You guys are kinda comparing apples and oranges ... or maybe walnuts and
almonds in this case. Yes there are mismatches when you move off the optimum
frequency of the antenna. In the case of transmitters, one generally finds
them operating on one or perhaps more frequencies in general proximity to the
resonant antenna in a 50 ohm match. In worst case, there might be a broadband
Tx operating in an entire band, such as 150 - 174 MHz into a broadband antenna
with a close match accross this range around 50 ohms.

A scanning receiver operates accross a much much broader range and no antenna
can possibly offer a good 50 ohm match, a good 75 ohm match , or whatever
accross this entire range. This means whether you're using 50 ohm or 70 ohm
coax doesn't really matter in the broad sense because both are going to have
mismatches from optimum impedance most of the time.

I have never EVER dealt with anyone as ignorant and blind as you, loony. You

Never have, never will.

Once again, irrelevant drivel supplied by you. That post had nothing to do
with anything.

Notice how you described yourself perfectly. You do this on a daily basis,
you moron.

Post on topic or SHUT UP, FOOL!!!! Nobody wants to listen to your drivel.

Thanks Ed, just ignore him. We all were doing just fine. Thnaks for clearing
it up.
