-- Original Message -- hello Mike, when I worked VK9LA on 30m on their second day, my "hpe 160" was answered by "sri, PA kaputt, no chance"... hard to believe that they have only ONE linear for 160,

hello Paul, I quite agree with Peter's (DJ7WW) advice, but instead of shortening the ends I would first fold them (tightly) back and check the result... "overshooting" can easily be corrected before

hello Bob, many thanks for the interesting tool calculating dipole dimensions.. it would be even more useful if it considered insulated wires as well... PVC-insulated wire can have an additional shor

hi Jeff, I wouldn't attempt to tune the radials exactly to resonance, because that will be most difficult to achieve due to a number of reasons... the worst that may happen is that just one radial is

we do not use WD-1A wire for our 2-wire beverages @CR3W any more as the attenuation of it (used as a 2-wire-line) is even higher than that of RG-58... we use 180m of the 300 Ohm flat line (of DX-Wire
