Automatic SWR and power meter
The display unit is awesome; Above all, the possibility of being able to assess the mean and PEP performance when the time constant is changing comes to my mind
Building a Coaxial Collinear Antenna
The Coaxial Collinear is rarely mentioned, It's design is super simple and since it needs no radials, it takes up little horizontal space its weight is negligible
Cobwebb revealed
The main advantages of the CobWebb over other 5 band 14 to 28 MHz antennas are that it is small, lightweight, strong madefrom fibre glass, only requires a single suppor needs no rotator
CTHA Antenna
Not having found any clear information about how design a CTHA for a specific band I decided to build one using the materials available in the shack just to investigate its behaviour
Build a Saltwater Dummy Load
Here is a simple solution the saltwater dummy load
