Building a 2:1 balun for Delta Loop Antennas

If you can't see the video, please go here:

This is post 2628 in a continuing series of simple ham radio antennas.

Thanks to Gil of the "" website for this useful accessory for delta loop antennas.

This balun will help you match the impedance of your HF transceiver to the slightly higher impedance of the delta loop antenna.

Here are some comments from Gil:

Delta loop antennas are awesome when you feed them well, either using a quarter-wave length of 75-Ohm coax or a 2:1 transformer, which I am building in this video. It works best from 80 to 15m, but will go up to 6m in a pinch as you will see being used with my Racal VRM-5080 on 6m FM. Update: Some people say this is a 4:1 and using the wrong core... Any experts here to comment? The antenna analyser shows 43 Ohms using a 100 Ohm resistor.
