Does anyone know the radiation resistance of a 55 foot vertical #12 wire, top loaded with 2 41 foot #14 wires sloping at 45°, with their ends at 35 feet?
There's a graph in one of the ARRL antenna publications, either the Antenna Book or the ON4UN book, of radiation resistance vs vertical height. I reproduced it in http://k9yc.com/160MPacificon.pdf
If the top-loading wires were horizontal, 55 ft would be the effective height. Their slope may reduce that a bit, but not a lot because there are only two and because the slope is not too great. I'd guess maybe 5 ft.
