A multiband Fan Dipole that works on 40 20 15 meters band, making a folded dipole for 7 MHz band and additional element for the 21 MHz and 14 MHz
An interesting and easy to build loop antenna for VHF bands, that present a feedpoint impedance of 50 ohms thus avoiding the need for a 1/4 wave impedance transformer. This antenna is ideal for sota and other portable operations
How to install a BNC connector on a coaxial cable like the ELSPEC1030AF / HPF195RG and 58C/U cables
This is a short version, the final of the article describing how to build the Weather satellite 137 MHz horizontal V-dipole antenna.
Current space weather condition gauges, with solar indices taken from the latest WWV report
This tutorial provides background information on the decibel and instructions for performing calculations involving decibels. This tutorial combines information from several authors, including Bob DeVarney, W1ICW; Walter Bahnzaf, WB1ANE; and Ward Silver, NOAX
A short 3 element LFA Yagi for 50MHz with a 1.94M boom. This antenna has been designed in order to minimise the upward and downward lobes typically seen the the EL plane on Yagi antennas.
