Here's a query for you more experienced inverted "L" afficianados...
Would I benefit from (possibly) optimizing the low angle radiation of my
inverted "L" antenna, if it was to be cut exactly 1/4-wavelength --- as opposed
to it being 170' long (overall), and tuned by way of a variable capacitor at
the base...?
I currently have a 3-element tri-angular phased array (135-degree phasing) for
160-meters: All of the elements are of the classic W1BB design, i.e. 170' long,
& resonated at the bases by individual variable capacitors.
I like this method of feeding the antennas, because I'm able to resonate each
"L" individually & exactly on 1.820-MHz, without the hassle of pruning /
trimming of any wire (a simple touch-up of the respective air variable
capacitor does the trick)...but I'm wondering if maybe I'm introducing more
high-angle radiation off of the flat top portions of each "L", than I really
want to...
Note: the vertical portions of each "L" here is about 70' tall...the horizontal
100' balance is true horizontal, away from the vertical portion.
Any & all comments / revommendations are solicited in advance of the coming Top
Band DX season...!
Thanks in advance, &
