[TowerTalk] Horizontal Loops

[Tim Kass]

Ive never used a Rhombic, but do have used alot of loops and currently using 
a horizontal Bi-Square, it radiates mostly upwards, on the designed 
frequency, 7200 khz, but practice and research states that as you go up in 
frequency with this same size antenna, the angle of radiation decreases and 
that is my experiece as well.  Worked other countries very well during the 
DX contect on 20 meters and 17 meters... it compared equally to my Hygain 
Hytower vertical.  The rhomic is very long and angles are important, I think 
it functions similar to a vee beam...so you need wavelengths of room... 73
