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 :-)
