Construction Cobbweb antenna

After the success of my first cobweb antenna I decided to build a rigid version for my home QTH

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 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

A simple SWR Meter is to be used at HF
