Brachiating Tetrapod
I am thinking about making a 12-15-17m fan dipole.
Similar to the Alpha delta DX-cc.
I have a straight line 67 foot space to mount this antenna, supported at either end by trees,
heighth wolud be 20+ at one end, and about 35 feet at the other.
It would cross over my DXCC antenna about 7 to ten feet above it at about a 75 degree angle.
Of course it will have to be slightly shorter to allow for insulators on either end.
So maybe I have 64 feet to work in.
The antenna would be three separate half wave dipoles (12-15-17m), connected to a center insulator that accepts a PL-259.
This is so I can feed the antenna with rg-8x or rg-8.
I dont't want to use an antenna tuner.
Does anyone have any suggestions on what center insulator or balun to use here?
