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.

Is this Ewe for You?
The article titled “Is this Ewe for You?” by Floyd Koontz, WA2WVL, published on QST February 1995 presents a simple yet effective receiving antenna design tailored for 80 and 160-meter DXing. As solar activity decreases, making MF and HF signals weaker and ambient noise stronger, serious DX operators seek improved signal-to-noise ratios through directive receive…
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.
Efficiency of the Z Match
Lloyd Butler VK5BR evaluated the power efficiency of various Z Match Tuner configurations across antenna load conditions, uncovering discrepancies in performance across different frequencies and load resistances.
Yaesu FT-991 Memory Manager
The FT-991 Memory Manager is a freeware program created by F6ECN designed to assist in managing, programming, and remotely controlling Yaesu FT-991 and FT-991A ham radio transceivers. It is compatible with Windows 7 through 10, on both 32 and 64 bit systems. While the primary user documentation is in French, the software’s latest version, 2.2.7.5, is available for download.
