Hi David;

I'm not an antenna expert, in the least, as most of my current MW DX'ing
is done with portables (though I have an old Sanserino loop in storage).
At any rate, have you considered a flag, pennant or some other corner
fed loop?  Bill Nollman (from CT, on the WTFDA lists) uses something
like a 30'x40'x30' corner fed loop and has so much gain that he has to
attenuate his antenna.  I'm just not sure about the steep angles of your
land.  You should be able to grab TA signals from WV as DX'ers from TN
and AL have heard them in the past.  I think that these corner fed loops
are similar to an EWE but they have a bottom wire and no earth grounds /
terminators, just the resistor on one corner and the transformer
opposite.

Nice AZ catch!

73,
Dave in Indy

noting that he'd have quit this hobby decades ago if it weren't for
phasing.

Yes, phasing is truly a remarkable thing.  I'm a latecomer to it, having
used indoor loops most of my DXing life, and now I don't know how I ever
lived without it.

 

I'm currently living pretty deep in the woods near the top of the west
side of a ridge.  I have room on my property for a LW of around 150 feet
running at around 20/200 degrees, which I have done at various times.
But the land to my east, up to the top of the ridge, is owned by the
Appalachian Trail Society and essentially unoccupied forest.  It's a
very steep climb and probably half a mile up to the trail itself, so
it's possible to lay a wire on the ground in that general direction
without bothering anyone.  I have one wire that was 500 feet when I put
it down, maybe four or five years ago, running more or less ESE, and a
new one about 200 feet to the NE or ENE, both on the ground running
sharply uphill.  The new one has noticeably better gain on most
frequencies, so I presume the forces of nature have shortened the
500-footer by now.  I'm planning to replace it when the weather cools
off enough for me to climb the ridge with a new wire.  Both are
connected at the near en!
 d with coax to the Quantum Phaser.

 

I'm no antenna theoretician, and I have no idea what an uphill on-ground
wire ought to do.  I probably could run a bit more than 500 feet ESE if
I wanted to, but there doesn't seem to be much point in trying to turn
it into a terminated BOG at that azimuth -- not many DX targets in that
direction, and it seems odd to run a terminated BOG up a steep ridge --
wouldn't the hill itself block signals in the target direction?
Anything much off that azimuth, and I start running into natural
obstacles or occupied land at well below beverage lengths.
