Hi, which of the commercially available 2:1 baluns in the 1 KW range would you reccomend for use in 40m and 80m Delta loops and who sells them? Is homebrewing much cheaper and who sells the parts? Th
The simple kit to homebrew is the easiest way to go, and costs $9.50 each. You have to add your own housing and connectors. Custom built, with terminals, SS support hardware and terminals, they are $
A simple cost-effective method of feeding 100 Ohm antennas such as Delta loops is to use an odd number of 1/4 wavelengths of 75 Ohm coax or a single 1/4 WL of 75 ohm coax followed by any length of 50
Assuming one wants to match to a 50-ohm coax for monoband use of the delta loop(s), why not first try a simple 1/4 wl section of 75-ohm cable? The delta loop may run between 110-150 ohms impedance, d
Hi all. I agree with Tom. The simplest way is to go with the 1/4 wave 75 ohm line. I have used that setup for years. If anyone saw how I did it, they would probably laugh. I just solder the inner con
Tom, Your coax splicing is a reminder that connectors are a convenience, not a necessity. A well done splice that passes muster mechanically and creates the least impedance displacement (even in 50-7
