The reason I am trying a horizontally polarized delta loop is because I had a
vertically polarized delta
strung from the tower and it was too noisy. The tower was reradiating noise to
the delta. I am using a wood pole extended out 4 feet from the tower
for the apex support and the lower section slopes away form the tower about 30
degrees. I did a temporary lash up with feed at the bottom for horizontal
polarization and 2 to 3 units quieter on the noise. Now I want to try linear
loading to reduce the size a little too. I would rather have the vertical
polarization for DX but don't like the higher noise level. So its all about
