whiskers are spaced at 5 3/4" in the vertical and 3" in the horizontal, they are 7 1/2" long - I know, I'm guilty, I copied the youtube, just to try - guess I was lucky that it got me all the US HD channels (UHF of course) and 2 of the 3 local HD channels!
My understanding is that I should have calculated the whisker length as follows:
- take the highest available channel wanted (#53, CBS) frequency - 700 Mhz
- calculate (300/700) x 1/2 = .214 m = 8.4"
calculate whisker vertical separation = say 8.4" - .4" = 8"
use whisker horizontal separation = 1 3/8"
use 10 gauge wire for the whiskers and lines, is that optimal?
I know I have many details, connections, stand-offs to improve...
also I noted that the reflector (24" x 30") did not improve my reception capabilites too much in any direction...
Does this make any sense, or should I try your 9.5" x 9" plans
Now that I am gaining more knowledge about the physics, thanks to people like you, I am addicted and have found a new hobby!
I plan on making a better version, or maybe build another type (SBGH..)
thanks for the HELP
