Hello to all,
I need your help on the next problem,
I have a 70 feet self-supported tower with on top KLM 5 el. 20m.
In my holidays I have mounted a inverted Vee for 80 m with KLM balun 1:1.
The antenna parameter are:
. length of each branch: 64.5 feet (I need the resonant freq. to about
3.780khz)
. height above ground on the center: 56 feet
. height of the tips above ground: 20 feet (aprox.)
. apex (branches angle): 90 o (aprox)
With this parameters, the SWR are minimum 2:1, at 3.730 khz.
There is nothing to be done for lower the SWR to a values near 1.5:1.
Last problem, one of the branches is hooked to my neighbor's tree (exactly an
Olive..HI..),
and I don't have many test in the backyard of my neighbor.
The question: any know a method to adjust the impedance of my inverted Vee?,
other than change the apex angle, antenna coupler, etc.
Thank you in advance and 73 from Barcelona.
