Mike,
In my college dorm, I had almost what you described in #3 -- access to two
separate gutter systems from two downspouts that didn't touch. In my case,
there was symmetry.
I was near the top floor (at four stories, a real New Hampshire
skyscraper). Connecting the pin to one downspout and the shield to the
other created a very ugly but vertically polarized lazy-H "thing." I used
C-clamps to make the connections between RA inspections. I worked Ducie
Island with it.
I'd recommend trying what you suggest in #3. It might work. It might not.
You'll definitely have poor ears in any case, though.
GL,
Mike N1TA

I'm doing a quick setup to try and load my rain gutters on 160. I've got
the general idea, but I've seen a couple of different methods, and wanted
to see if any of you have done this and your thoughts on another possible
configuration.
1. The basic configuration is connect the center conductor of the coax to
the gutter and just go with it.
2. I've also seen a configuration where the coax shield was then connected
to a radial field (I do not have one available), so this is not the likely
scenarion.
Both of these configurations have been done connected to the end of a
downspout, so the antenna is basically end fed.
I have 2 downspouts that come down together, but then go different
directions, providing me with an extra 50' or so of gutter.
3. Would it be better to connect the coax shield to the other downspout and
try to go with an OCF type of situation, since one gutter side has about
50% more length to it?
This is not my normal antenna for 160, just something I want to try this
weekend if I can make it work.
73,
Mike ND9G
