It seems that from the discussion about v's vs flattop that the flattop may be
quieter. However when height of support structures becomes an issue is it
better to use an inverted v with an apex at least a 1/2 wave above the ground
or a flattop an half that height. I understand that antennas that are too low
can be cloud warmers so is it feasible to use a flattop that is too low for a
receive antenna and an inverted v at proper height for a transmit antenna? I
have 1 tower at 60' in the center of my lot and 2 others at 25' at either side
of the lot for end supports. The 25' towers are limited in height due to power
line clearance. The dipole wires lay 150 degrees by 340 degrees. I have 2
separate dipoles 2 feet apart fed by separate coax feeds with no baluns or
chokes for 80 and 40 meters. My noise level usually runs around s 5 on 20
using a beam at 60' and s9 on 40 on the dipole and s9+10 on 75. the sweep
display looks like a pocket comb on 75 and not much better on 40
. No weak signals worked here.
