Ultimate Portable HF Vertical Antenna - A light and compact antenna that is easy to build, and easy to find parts for. Band coverage is 60 through 10 meters.

Radial systems and ground - Radial systems for elevated and ground mounted vertical antennas by SteppIR

Antenna Gain versus Height - Antenna gain for horizontal, vertical, and tilted orientation of a dipole for heights between 5 and 50 feet.

KC1XX Contest Station - Amateur Radio Station owned by Matt Strelow. The station is designed for competition in the multi-operator multi-transmitter category of high-frequency DX contests. Running with 7 towers 6 rotators, 8 beverage listening antennas, and 4 spotting verticals

Cross-Yagi antennas - For two purposes a Cross-Yagi can be useful Satellite work or if you need both vertical and horizontal polarization for terrestrial contacts

6m Half wave vertical - This antenna is very useful for receiving or scanning purposes, but you can use it for transmitting, too. It is 2,94m long and has a pi-configuration (Collins-Filter) for the matching.

Balloon-supported verticals - Using balloons to raise lengths of wire can be great fun - as well as making it possible to work the DX on 136 kHz from small gardens.

IPS - HF Systems MUF maps and prediction charts - These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts for Astralia and Asia, Europe and North America

NEC4WIN - NEC4WIN is a 32 bits commercial antenna simulation software based on MININEC3 developed by the Naval Ocean Systems Center in the 70s and 80s. It runs under Windows and can be used to simulate, analyze and optimize wire antennas, beams, verticals, etc. NEC4WIN has limitations. They are the same as Mininec3 on which the engine is based.
