144 & 432 MHz High IIP3 LNAs
When I first saw the article in , I was very impressed with the data and quality of the construction

Below is my old dipole
This is a good antenna!! Very well made and strong enough to last through ice storms
Bolometer 10GHz
When building an ATV Transmitter at 23cm, the need for a power meter for small powers arose
Condensatore variabile auto-costruito
La costruzione di un condensatore variabile utilizzando delle comuni basette ramate per circuiti stampati ed una lastrina d’alluminio
Construction Details for 50MHz-Yagis
The 50MHz-Yagis are designed with an impedance of 12.5 Ohm or 28 Ohm and some types with 50 Ohm impedance, the 12.5-Ohm-Yagis are designed with small bandwidth 300 KHz at highest
Controlled Impedance "Cheap" Antennas
The antennas were designed with YagiMax, tweaked in NEC, and the driven elements experimentally determined on the antenna range
