A small, easy to build, copper tube magnetic loop antenna for the 2 meters band. In Italian
When experimenting with the WellGood Loop antenna, I came across the PA0RDT MiniWhip design referenced in several places. The construction of the PA0RDT MiniWhip is simpler than the WellGood Loop since there are no inductors to wind, but during my testing, I have found the loop to have slightly better performance.
This is a simple half wave antenna for 70 cm band, made using the jpole design.
This article describes the construction of a 100-Watt, 70 cm amateur band linear power amplifier. It is the result of a protracted period of experimentation during which I investigated a number of final amplifier stages from obsolete UHF FM 2-way radios.
A complete guide to start operating EME. In this document, that is the result of several years of experimenting, the author summarize the steps to begin on Earth-Moon-Earth communications
This stacking offers a well known simple phasing technique. All elements can be fed in parallel by open wires provided that they are fed in phase. This can be achieved by twisting the open wire phasing-lines at 180 degrees.
