RF Power Watt Meter
This video will describe how to use a simple RF power watt meter to measure output power of any radio transmitter from 1 MHz to 8000 MHz
Simple Wideband SWR Meter
This is a circuit of Wideband SWR Meter. This circuit is used as a test instrument
SWR Bridge
The resistive SWR bridge is highly recommended for both beginners and experienced constructors

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
