Cobweb Antenna omnidirectional
It comprises 5 parallel dipoles bent into a square shape and mounted on a support structure made of fibreglass poles

Cobweb Antenna
The wires above are 12-14 AWG basically speaker cables which are cut to 1/2 wavelength for each band the area of the band you are interested

Cobweb Antennas
These are my SWR readings so far: 28.782→ 1:2 - 24.248→ 1.2 - 20.633→ 1:2 - 17.664→ 1:2 - 14.079→ 1:1

Ultra Light Cobweb Antenna
Cobweb Antena is the best omnidirectional antenna for 6m, 10m, 12m, 15m, 17m, and 20m HF Bands


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

Rx antennas 4Square Rx Vertical Array
