- My favourite HF band is 20m
- Delta-loops for 20m are manageable in size
- Loops are quiet on receive
- Vertically polarized loops are well suited for DX
Delta-loop overview.
My choise of shape will be version D because if offers a low radiation angle, which is necessary for DX. The sketch below shows how I plan to build the antenna:
Delta-loop antenna for 20m.
A delta-loop antenna with ATU was described by WB8IMY and published in QST May 2002: One Stealthy Delta. This article is worth studying if you consider constructing a loop antenna.OZ1BXM Lars Petersen
Thanks for that, am considering the same for better 20M performance. What is the balun used, 4:1?
SvarSletThe ideal balun is 1:2, but 1:4 will do. The ATU will compensate for any mismatch. 73 de OZ1BXM Lars
SvarSletHello Lars
SvarSletThnx for that, is it possible to change the baluns 1:4 with coaax 75 ohms and then coax 50 ohms, 73 de 7X2GK Kamel
