Topband: 4SQ antennas directions

[Jorge Diez - CX6VM]

Hello Guy

 

Not understand at all

 

Did you say that I can put one antenna at 35 and other at 325?  This is a 70 degrees difference, not 90.

 

73,

Jorge

Midway between 25 and 55 is 40.

 

Midway between 310 and 350 is 330.

 

Rotating counterclockwise 10 degrees from the 45/135/etc common USA settings would give you NE and NW pattern centers at 35 and 325.

 

35 and 325 is very close to 40 and 330. It will bring far west USA up from 30 degrees off center lobe (-1 dB) to 20 degrees off center lobe (-0.5 dB), for a half dB improvement. It's also mildly better for Scandanavia and Asiatic Russia. 

 

If the orientation is entirely arbitrary, then might as well get the half dB. They didn't get 45/135/etc from the Bible. It's just the direction to Europe from my part of the globe. 

 

What gets done about the counterpoise for 160m verticals, excellent vs. poor, will make far more difference.

Hello



What´s the width angle of a single antenna in a 4SQ system?



In USA I have W6 at 310 deg and W1 at 350 deg.



In Europe I have:

-          EI, GI, GM at 25 deg

-          CT, F, DL, EA, PA, EA8, UA1 at 35 deg

-          OE, OK, HA, OM, UA3 at 40 deg

-          6W, 5T, I, E7, 4O, YU, UA4 at 45 deg

-          LZ, SV, UA6 at 50 deg

-          5N, TT, SU, YI, SV9, SV5, TA, at 55 deg





Classic setup will be antennas at 45, 135, 225 and 315



But this will be the best positions from me?  For Europe 45 degrees will be
OK, but not sure about 315 degrees for USA



If I change USA antenna at 325 deg, I don´t think Europe at 55 degrees will
be the best



What would you do in my situation?



Thanks in advance



73,

Jorge
