All, is important to keep RX antennas like flags, pennants and K9AYs as far away from TX antennas as possible. In the case of a quarter wave important to keep section as the vertical section? guidan

Hi Paul and fellow Topbanders, The answer IMHO is leave it at 1/4 wavelength. Adding wire to a 1/2 wl antenna will make a Hi-Z point at the feed point which your tuner could have problems matching.
Fellow Topbanders: Another Hi-Pass filter is shown in the 1986 ARRL Handbook on page 30-24. It is also shown in other ARRL Handbooks. The original article was published in QST in Feb 1978 and was w
No, but if a variable capacitor is used the reactance nul can be moved up or down the band for resonance. This can also be done with a 5/16 wl inverted-L which usually comes in close to 50 ohms resi
Rob: A typical 3/8 wl inverted-L antenna is about 65 feet vertical and 125 feet horizontal or sloping back downwards at a slight angle. This means that 2/3 of the wire is horizontal near the ground

Hi Mike, et al, Here are my thoughts interlaced. **Using a wire - say 12 gauge - Will probably give you a 100 kHz 2:1 SWR bandwidth. Using a vertical say 2" O.D. at the bottom and 1.25" O.D. at the t
Hi All, IMHO, 150 feet of beverage for 160 is too little. I would prefer a pennant or flag loop antenna aimed at Europe. It works! Also, being only about 30 feet in length, one can keep it on one's p
