Double Half Delta DHD
This is a DHD Double Half Delta in theory it should return a low signal but with a good S - N ratio roughly like a Beverage
Double half delta loop for low bands
A few days ago I had the time to build and try a Double Half Delta Loop (DHDL) at our Contest Station ED1R. The Antenna was built within 3 hours and can be deployed errected within 20 minutes
A 160 Meter Antenna Hybrid DesigA resonant antenna on the 160 meter band in less space
EWE-KAZ antennas
The Kaz Antenna operated very similarly to the Pennant
Fabricating Impedance Transformers for Receiving Antenna
Impedance matching transformers with isolated windings, he ferrite core types 43, 73 and 75 had all been suggested
