Two seperate questions resulting from discussions at the last ham club meeting I've been to:
1. Using 75 ohm coax to transmit. Although it's something I would never do, the discussion centered around the match you would get. If I have a 1:1.5 match with 50 ohm feedline, is the impedence then either 33.3 or 75 ohms? And if that is true, then if I was to use 75 ohm coax, would I just get a 1:1.5 match? You see where the discussion went.
2. Half wave antenna on a fiberglass van. Let's say I drill a hole in fiberglass, like the top of a van, or maybe a boat, or even a piece of wood, in other words, something with no ground plane. And I put a half wave whip on it. Should this play just fine?
Come spring, I'm gonna put new batteries in the MFJ analyzer and play with both scenerios myself, but while I'm nice and cozy with the heater, I thought I'd throw out this for discussion.
