No room for 1/8 wave spaced inverted vee's with about 145 degree phasing to
kill all the high angle and get some decent gain?

Subject: [Amps] QRO operation into a 80 meter vertical
Slightly OFF TOPIC , so respond direct please.
I have a 145 foot Rohn 45G with insulated guys, but grounded base in
concrete.
no room for radials ... 33 feet at most over 60 degrees.
Tower is between hamshack ( house ) and garage
and concrete drive ( 300 degrees = no radials )
I would like to experiment with a ground independent (or less ground
dependent)
1/2 wave vertical radiator ..... a vertical dipole hung from 145 feet,
maybe six feet from the tower face or leg. Fed in the center or at the
bottom.
Similar to a sloper, but closer to the tower. Maybe connect the dipole
to the top of the tower and feed it like a folded unipole ?? Open to
all suggestions.
I'd love to hear how you constructed your high impedance tuners too.
