i just planted my first topband antenna. a homebrew extended length butternut 2 v with homebrew tbr160 coil on a 30 feet pushup mast to help me squeeze a slooping radial in my 40 feet x 45 feet tiny terrace. i was able start my 160m dxcc ac with a ua4 on lotw. Want to add one more hf9v and convert it into a 2 el phased array for 80m with a compromise spacing of 50 ft (max diagonal spacing available). rx is a challenge. max allowed power of 400 w dc input to final in vu land is another challenge. i plan to build a dual waller flag http://nx4d10.wixsite.com/waller-flag/page3 and place it as far away from the diagonal line of the phased array as possible. what kind if interaction/detuning/directivity hit should i expect. for 160m/cqww cw contest weekends i can try installing the flag in my neighbours terrace temporarily.
assuming i add another tbr160 to the 2nd hf9v can i expect any directivty gained by the 80m phasing on 160m. i will keep the linear happy by using a tuner. has anyone modelled something similar? any tips/suggestions welcome. 73 de Aravind vu2abs On 23 Sep 2016 01:19, <daraym...@iowatelecom.net> wrote: > Success also depends a lot on your location.
