The CobbWeb Antenna
G3TPW CobWebb Antenna for the 14, 18, 21, 24 and 28 MHz Bands Author and source: http://www.g3tpw.co.uk/ The main advantages of the CobWebb over other 5 band 14 to 28 MHz antennas are that it is small, lightweight, strong (made from fibre glass), only requires a single support, needs no rotator, gives full size dipole
J-vertical Antenna for 10 meters band
Article by EI9GQ My first J vertical was a Slim Jim for two metres. This simple aerial performed better than a centre fed dipole at the same height. I compared it with an end fed half wave and an end fed 5/8 wave vertical. The Slim Jim always gave better results. SLIM JIM When I
6m/10m Dual Band mobile whip
This antenna is made from either an old CB whip or a stripped-down 2m 5/8 whip. When you strip down and re-shrink an antenna, be careful because some heat shrink tubes can change the antenna’s resonance, especially with helical windings. You can use a piece of 20mm conduit for the former of L2 with a

VK5AH – HF 4 Bander Antenna Construction & Adjustment Tips
In this article, VK5AH shares his know-how on building and tweaking the HF 4 Bander antenna. Packed with practical advice on setting it up, making adjustments, and understanding its performance
40m/80m Lake Eyre Portable
While camping by Lake Eyre, VK5AH invented a new antenna, better than the mobile whip. It clips onto the mobile mount and is hoisted onto a nearby tree. It works well at a 45-degree angle and can be adjusted for 160 meters.
G5RV All-Band HF Antenna
This article discusses the characteristics of a 102 ft. center-fed dipole antenna strung between two 37 ft. poles. It explores predicted feedpoint impedance variations across different frequencies and the corresponding impact on the VSWR for various feedlines, based on EZNEC antenna modeling software predictions. It also analyses how alterations in element lengths of antennas significantly affect their performance at higher frequencies.
