Hello everybody I need your help please. This summer I will erect a new 100ft tower to place 80M3A of M2 on the top of it. Need to use the same tower for placing as high as possible without seriousel
Hi Gia, With regard to colocating 80m and other band antennas: Several years ago I had a similar discussion with Mike Stahl at M2 and did some extensive modeling with Al Christman K3LC. The general f
Hi Scott Thank you for your quick reply and sharing this very important info...well I am quite dissapointed. Any solutions with the distance between two antennas? NO I don't have space for 4-square I
All is not lost... There are ways to approach this... First will be to rotate the 80 array at 90 degrees from the 20 array... While this will not stop all interaction it will diminish it... Next is t
Detuning can certainly reduce interactions. But there is no free lunch. Adding relays to the linear loading wires adds additional points of mechanical and electrical failure to the system. And those

While the antenna is down, it would be beneficial to replace the loading stubs with coils. Gives significant improvement in antenna performance, especially cleaner and better F/B pattern. There was a
My limited experience at my new QTH on 160 (one season) with both a horizontal dipole at 90 ft and a 70 ft top-loaded vertical with 40 70-ft radials is that the vertical is at least 10 dB better with
I would like to thank you all for your asnwers, was good idea to post this question here I was strugling with quite some time. All suggestions are pointing to the right direction and quick conclusion
