| Ever heard of stacked, folded dipole arrays? Not uncommon at all. <G>
Of course not. But on a general purpose amateur repeater it would be
uncommon, unless you're trying to link to a repeater in the next city
(which is certainly something that people do from time to time.)

Sure. But does that make a vertical dipole high gain? The EME guys?
They use high gain antennas. Satellite guys too. Even the HF DXers
do if they can. But most repeaters just keep the signal in the
horizontal plane and don't want to be more directional than that, and
I'm not sure I'd call that high gain. Though I guess it's all a
matter of how you define `high gain', and certainly not worth arguing

Depends on the repeater. And I said often, not all ...

I said repeater inputs. There's a R/C channel at 50.98, and the
repeater inputs start at 51.12 -- that's only 0.140 mHz away. (I'm
http://www.arrl.org/FandES/field/regulations/bandplan.html#6m , in case
that's not obvious.) (Though in the 72 mHz band, you could easily have
a pager tower output only 10 kHz away ...)
I'm not sure how many repeaters actually use that part of the band,
but it's there on the band plan, and if you're trying to stay away
from the repeaters, you should stay away from the inputs too.

| There are 50 MHz beacons, not repeaters.
Sorry, I wasn't specific. In that case, when I said 50 mHz, I meant
50-54 mHz or the 6m band. And what I meant is that there's not that
many 50-54 mHz repeaters out there, at least not compared to what's on
the 2m and 70cm bands.

No. But I'm not sure how it's relevant.

Are we discussing electronics? Or credentials? I didn't think so,

Was I even questioning your knowledge of the subject? (see? I can
ask rhetorical questions too ...)

You were clear. (Why would you ask for the callsign of somebody who
hadn't even posted yet?) I guess I wasn't. The original poster's
callsign is given in the name field of his posting, and you quoted
that when you quoted his posting. I highlighted that for you above,
but I guess you missed it. It's still there -- in the thirteenth line
in the body of this post. KG6YKL is Carl's call sign, if you missed
