Vertical antenna multiband to trappes


It is omnidirectional and multi-band and is well suited to DX enthusiasts who have little room each of the parallel circuits hatch behaves as an isolator on its resonance frequency. Thus in the example of the figure opposite, when the antenna is fed by a 28 Mhz signal 10m band) the 10m trapdoor insulates the segment A of the upper part of the antenna segments B and C.

The plain and simple truth is that wire antennas for the HF bands were intended to be hand-made and not store-bought

2 element reversible vertical
32ft. long insulated wires supported by fiberglass push up masts at aprox 40 ft high

80m-40m Dual Band Vertical
Hopefully this will help others looking for a good 80m/40m antenna. I have enjoyed this antenna project and it works very well

20m & 40m trapped vertical squid pole antenna
The trap is made with 42mm diameter PVC pipe with 9 turns of wire on it. In the middle of the pipe is a length of open ended coax acting as a capacitor

2 element reversible vertical
My linear-loaded vertical doublet has been doing an excellent job the past two years, but it's time for a change. I've wanted to play with a twin-T capacitive loaded vertical doublet design
