Ham Radio: Low bands (160, 80, 40)

Estimating T-network losses at 80 and 160 meters.
Originally published in QEX, this article discusses low band issues with the t-network, popular at many ham radio stations today.

F5VKM Low Band DX Antennas provides materials for constructing kite or balloon antennas for low bands.

Do you find it hard to get on 160 meters because of the antenna? This simple wire may be just what you need.

Gary Breed, K9AY, developed this loop for lowband receiving. It is known for its ability to compete with large beverage antenna systems in terms of directivity and low noise.

The Shunt-fed Tower, An Effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M. This article describes the process of shunt feeding your ham radio tower for low bands.

Shunt Feed tower for 80m 160m. This article from May 1975 Ham Radio Magazine describes a graphical or charting approach to designing a shunt feed system for low band operation on a typical ham radio tower that is topped with antennas.

The Myths of Low Band DXing by Gerry VE6LB. Includes tips on low band dx operation for hams.

Titanex (Germany) produces a wide range of HF antennas including Log Periodics, Cubical Quads, Yagis, Verticals (including a 26.7m high free standing antenna for low bands), towers and accessories. Titanex has a ham radio distributor in the United States (Array Solutions) to minimize radio tower shipping/import costs for American hams.
