160 Meter Vertical - This is a 90 foot tall top loaded vertical for 160 meters. It is constructed from aluminum irrigation tubing and has four sets of four guys each by w7iuv

Broad Band Dipole for 80m - Mesh constructed with enamelled wire 0.5 mm diameter For installing a support (plastic rope 2 mm) is needed. Antenna used on Solomon Isl in 1995 H44/DJ9RB

A Cost Effective Current-mode 1:1 Balun - A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors.

This Old Dipole - An antenna construction workshop conducted at Marshall N1FN's QTH

Dipole Calculation - Determining your proper length for the open half-wave dipole antenna

T2FD, The Forgotten Antenna - The terminated. tilted, folded dipole T2FD is a little known antenna that performs excellently. Compact in size compared to a half­-wave dipole the T2FD provides signal gain, wide frequency coverage, and exceptionally low noise characteristics.

KB1SG's Rhombic Pages - Great pages about KB1SG rhombic antennas collected by EI8IC.

Secrets of a Successful Stealth Operator - N5IW ideas to build your own antenna in a restricted lot, or a stealth antenna. Includes PPT files of HF and VHF stealth antennas.

VE6YP CoaxTrap - The Coax trap program computes design parameters for the construction of coaxial traps for HF usage. Typically these are constructed from PVC tube and RG58/59 coax

HB9DHG QSL gallery - Fully seachable and ordered QSL cards gallery includes front and back of thousands of QSL cards received by HB9DHG

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

Millenium QSYer - The Universal QSYer KeyPad works with both ICOM and selected Yaesu radios, extends these capabilities to owners of the Yaesu FT-817, FT-897, FT857, and FT-100. Additiona features for Icom Radios

The Baudot Code - Table that represents programmer's quick reference to the Baudot character set.

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.

TLDetails - Transmission Line Details. This utility program shows the impedance and SWR at both ends of a transmission line and the details of power loss in the line. It includes characteristics for over 40 built-in line types. You can modify these values to see how small changes affect the results or to specify custom lines. All program inputs may be changed directly or you can use spin buttons to make the changes. If you are using a moderately fast computer you can hold down a spinner and "watch the movie" on the charts as the results are recomputed. By AC6LA

TubeCalc - Input (grid or cathode) and output (plate) tube resistances calculation according to its electrical characteristics, frequency, mechanical dimensions and working conditions.

VHFCtest4Win - VHFCtest4Win is software for contest logging QSO's on VHF bands (50MHz and up). It is build for all windows versions from Windows 95 and up. by S52AA

Contest Log Converter - Contest Log Converter it's a Windows program that allow to convert data file between the most used Contest Log. The program allow you to convert 12 different type of contest, selected from the common contest managed from the Contest Log program. The follow program ,CT by K1EA, TR by N6TR and NA by K8CC are full supported with the conversion of the most famous world contests.

glfer - glfer is a program for reception and transmission of QRSS/DFCW signals. It is composed of two main parts: the spectrogram window, where you can see the spectrum of the received signal vs. time the transmission functions, to emit cw characters at a slow but precisely controlled speed, using the QRSS (slow CW) or DFCW (Dual Frequency CW) modes

Simple adjustable passive attenuator - This adjustable passive attenuator works as a "waveguide beyond cutoff." It can be constructed in about ten minutes from parts available locally.

Idiot's guide to coaxial cable  ^pop - A very beginner's guide to coax cables. Characteristics, detailed comparison of typical coaxial cables, commonly used connectors, and a few words about SWR.

Coax cable data - Characteristics of commonly used transmission lines
