Hi Gavin.
I put up 40' of 1-7/8" + 2" aluminum tubing and hooked a 40' wire to the top,
trimming to get the SWR where I wanted it (not too much trimming was needed;
sorry, but I didn't measure). 60 short buried radials, hairpin (inductive)
match. 60' wide city lot, houses all around.
I did CQWW CW as single band 80 HP and got 89 countries. MUCH better than with
my low dipole.
