300 ohm twinlead 40 meter dipole - The N2CKH travel special 300 Ohm ladder line convertable antenna

A $20 HF mobile antenna - A few hours of fun with PVC and wire and you’ve got yourself a respectable road radiator. The antenna consists of little more than some PVC pipe topped by a RadioShack replacement whip antenna and a couple of coils made from a small roll of #14 house wire.

Field-Deployable Antennas - Resonant dipoles, the W3EDP and end-fed wires, the extended double zepp, non-resonant doublets, and the "Zip-Cord Special" , the W6MMA vertical.

Bell Tower - Broadcast Tower Specialist. Offering Manufacturing, Engineering, Erection and Tower Extension Services. Self Supporting or Guyed Towers.

Longwave operations - In the VLF portion of the spectrum it is easy to listen to the emissions created by the Earth itself. These emissions are generated by many different mechanisms and are often beautiful to listen to. Coverage on LF and MF frequencies

Amsat DSP Satellite Transceiver Project - The DSP Satellite Transceiver is a conceptual transceiver designed as a dedicated unit for amateur satellite operators. The initial concept was brought about by the lack of satellite functionality on modern amateur radio transceivers, and the specialized requirements of the ham radio operator who utilizes OSCAR amateur satellites.
