W7AV 40 Meter Half Square - These antennas offer big gun DX performance on the low bands, yet they are surprisingly simple to build. Try one- you will like it!

20 meters Cage Dipole - Cage Dipole is based on the fact that a wireframe does emulate a tubing of the same diameter, supposed that the wires in the frame are close enough to resemble a solid surface.

Measuring Cable Loss - Improving measurement accuracy when low-power analyzers are used.

Better Feedline Loss Measurements with Antenna Analyzers - Various publications through the years have shown how the SWR measured on a shorted (or open) feed line can be used to calculate feed line attenuation

G5RV antenna - Review by G3TXQ and comparison to its modificated versions. SWR Measurements on inverted V setup and comparison from EZNEC model and a real one.

CSVHFS Antenna Gain Measurements - The Central States VHF Society has conducted Antenna Gain Measurements since its inception in 1967. Comparisons between commercial and homebrew antennas, between different homebrew designs, and between different commercial designs. Mostly VHF UHF and up antennas.

W7ASU ARS at ASU - The club consists of about 30 members who are interested in amateur radio and the surrounding activities.

Mortality statistics in Ham Radio Community - To search for potentially carcinogenic effects of electromagnetic field exposures, the author conducted a population-based study of mortality in US amateur radio operators

F8BRL, Sylvain - Personal site de F8BRL, Sylvain, station radioamateur de Monchy saint Eloi Oise

Peet Bros Company - Manufacturer of advanced electronic systems to measure such weather data as: wind speed, wind direction, wind chill, pressure, humidity, rainfall, and dew point.

LEMO Connectors - Lemo offers over 50,000 circular connectors for a variety of industries including medical, military, and test and measurement.

DEHN, Inc. Surge & Lightning Protection Priority listing - Offering transient voltage surge suppressor, TVSS, patch cables, surge arresters, surge protectors for lightning and power surge protection for electrical equipment, IT networks, communication systems, data lines, relay systems and solid state controllers.

ARDF transmitter for 80 meters - The 80m TX described here is the well known ON7YD ATX-80 and timer, combined and re-engineered to fit a readily available enclosure by G3ZOI

Circuit Improvements for the TL-922 - by Richard L. Measures, AG6K

Government Liquidation - Government Liquidation is an online marketplace for the sale of U.S. Government surplus and scrap material to the public

A1PARTS - Canada's Largest Electronic Surplus Store

Oplink solutions - Repair and refurbish electronic test & measurement equipment.

Meter Mate - SWR Graph Software - Meter Mate is a companion utility for your directional watt meter that allows you to calculate the SWR reading when the forward and reflected power readings are measured. In addition to calculating the antenna system SWR Meter Mate will also plot the SWR curves of all of your antennas onto graphs that may be printed out.

RevLoad - This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immmediately see the R and jX values of the load on the network, presented as both a schematic with the component values and as a Smith Chart normalized to the specified system impedance.
