I use my 80 foot doublet by tying the ladder line together at bottom and
feeding against ground+radials as a "T", in every 160 contests with excellent
results. It helps that mine is up 75-80 feet but even if yours was only up 40
feet I'm sure it would be fine.
80M was in excellent shape last night, despite ongoing local thunderstorm I was
hearing lots of EU, and I was being spotted all over western EU with excellent
levels at just 100W out:

Subject: Add top loading or invert-L 43 ft vertical

I would like to try my hand in the 160 contest this weekend. My antenna is a 43
ft vertical. I don't intend to use it as-is or add a base loading coil. I have
heard of adding a wire to the top to act as an inverted-L or adding several
wires to act as a top-hat. I will be using the internal tuner in my K3 and
running 100 watts. I have 60 radials, mostly 43 ft and a few 60 footers. I
don't have many options for supports but could put a 23 ft fiberglass mast
temporarily at my shed about 100 to 120 ft from the antenna and run a sloping
wire. Which might be more effective? What wire lengths should I try?
My only other option is an 80 meter doublet fed with ladder line that put up
for Field day. If I put it up it wouldn't be very high.
For receiving I have a magnetic loop.
Any suggestions appreciated.
