This is my Inverted-V portable antenna for 20m. It consists of :
a) Spiderbeam HD 12m fiberglass pole with clamps
b) MFJ-1779C center insulator for dipole wire antenna
c) two black isolated wires with diameter 1mm2 cca 5m long
d) two plastic dog bones
e) two ropes
f) coax cable Aircell 5 - 50ohm
The antenna is resonant approximately at 14.180 MHz, SWR is about 1.2, was tuned using MFJ-269 Antenna Analyzer and it works fine using just 5W with Transceiver FT-817ND.
I use it mostly for portable operation.
