How To Build Cheap Wire Delta Loop Antenna
One of my favorite HF antennas is the easily-made, inexpensive delta loop. The antenna is quiet and offers some gain over a dipole. In this video from Callum (M0MCX), we learn how to design, build, and test this versatile antenna. You can get multiband performance from the delta loop if you feed the antenna with 450 ohm ladder line and a 4:1 balun. Good monoband performance can be obtained if you use a length of 75 ohm RG-6 coaxial cable as an impedance transformer for your regular 50 ohm coax feed line.

Here are some comments from Callum: Lots of myth about vertically polarised delta loop antennas - lets take the covers off and have a look. Callum. DX Commander.
