Re: Coax cable for long run up mast

The capture effect is a function of power, not audio, e.g., you can capture an FM receiver squelch with an unmodulated (no deviation) signal. Audio intensity field measurements are entirely different...

Re: Coax cable for long run up mast

Assumed you would do your own research. None have an AGC circuit as it isn’t relevant or useful for FM.

If there is a marine VHF which does, it’s a dual use radio for SSB or AM reception.

Re: Coax cable for long run up mast

Actually, it doesn’t but the explanation is beyond what is appropriate on a boat forum. The internet is full of links which explain the distinction.

Re: Coax cable for long run up mast

You must be a new ham. Time to ‘hit the books’.

We’re not talking about audio level. We are discussing a power function which is entirely different. While you cannot hear a 1.5dB audio...

Re: Coax cable for long run up mast

Belkin coax? I wasn’t aware that Belkin makes coax transmission line. Are you confusing that with Belden?

Re: Coax cable for long run up mast

Good choice. If it was me, I’d ask them to use soldered PL 259 connectors (which is an option indicated), not the crimp ones as they are more prone to failure in my experience. The crucial aspect of...

Re: Coax cable for long run up mast

It’s your premise which is wrong - there is no such thing as “enough” under varying circumstances, conditions, distances, etc... it will always be a difference answer.

“Enough” is whatever is...

Re: Coax cable for long run up mast

First, a 25 w radio doesn’t radiate 25 w at the antenna. Second, sometimes, 25 w isn’t “enough”. More important than 1or 2, it’s 20% or more of the signal lost as coax loss and saying its “only 1.5...

Re: Coax cable for long run up mast

Very misleading....


That’s roughly 20% of power. That can be a “big whoop” under marginal conditions.

Also, connectors if properly installed have no inherent loss.
