Some of my best, and easiest, 160 DX has been to the Antarctic area and
surrounding islands with a coax fed 160 inverted V with the apex at 60' and
the ends at 3'.
Apparently NVIS into a duct with little attenuation since it rarely took
more than a coupleof calls. Im also on a hill in the country here in NH.

I have always used an 80m inverted-vee (66.6 ft per side) with apex at 50ft
at top of a yagi-free tower attached to a steel workshop and fed with 450
ohm ladder line and shorted at the tuner in the shack to work as a top
loaded vertical (35ft is actually vertical, rest of the feedline mostly
hortizonal 3ft above a steel roof!
Just worked JA8EAT with 100W on March 12 at 1040Z (thanks Yaz for LOTW
confim and number 131 QSLd on topband...138 worked in 10 years). No 160m
amp here....yet. Use 16 radials (100-130ft) and temporary winter 600ft
Beverages and 200ft Bogs for RX. Helps being on a hill in the country as
well. I always feel loud in the ARRL contests to the West Coast and KH6,
but usually have to wait past 0300Z to work any EU even though I hear them
at my sunset.
So are the others (Brian?) talking about a true coax-fed 160m
inverted-vee? If so, I'm interested!

I put up a 1/2 wave Inverted V ( each leg is about 140' ) for 160M in
January of this year just so I could do inband SO2R in the CQ160 CW
contest. It has its apex at 40' and the ends are at 5'. I would have been
very happy to just work any East coast stations during the contest but I
found that I was being called by stations from as far away as California
down into the Caribbean and everything in between.
This morning I worked Luke ( VK3HJ ) on my Inverted L here at 1110z (
SR-5 min ) and we exchanged Q5 reports - nothing unusual. Then at SR he
disappeared into the noise. Again nothing unusual. After a java refill I
came back into the shack and could hear NA stations calling and working
him but he was still NIL - not even a single ping could be heard on the
Inverted L. Just for fun I switched over to the Inverted V and there he
was 539 to 549 - a real booming signal almost as loud as when we worked
earlier when I gave him a 559 on the Inverted L. Now it was SR+28 min so
when there was no one coming back to his CQ's I called and I almost fell
out of my chair when he came back to me. No we didn't make the QSO as he
didn't get my full call but the fact that he heard anything is amazing.
Had I been running more than 100 watts I have no doubt we could have
finished the QSO.
So the Inverted V definitely stays up.
Carl I am a believer :-)
73,
