- Jose, You only need about 2 to 2.5 degrees of downtilt. If your antenna is produced by one of the major antenna builders they should be able to provide you with feedline section lengths for the requi

- No, you will need to tune the lengths of each vertical. The parallel circuit does not tune the antenna - it only provides matching. It's not likely to work very well as the feed impedances will be g

- The Hy-Gain DP-19PD is not a tape dipole but it might be a useful "modern" replacement. See the Hy-Gain web site: http://www.hy-gain.com/products.php?prodid=DP-19PD 73, ... Joe, W4TV ________________

- Ed, Lengthening the counterpoises would definitely cause a problem and detune the antenna. The traps and/or top loading of these "3/8 wave" antennas are really designed so that the antenna acts like

- I would also suspect re-radiation from the inverted L - particularly since directivity falls apart as the frequency moves closer to the "resonant" frequency of the inverted L. The vertical wire on t
