[amsat-bb] Coax run on the Beams

[Prathap Kumar]

Hi All
I have a question regarding the coax run on the boom or cross arm supporting 
the Vhf and Uhf beams.
All these years I was feeding the coax to the beams running it backwards and 
allowing it to drop behind the relector downward as suggested, that it does 
not affect the performance.

But most pictures I see these days have the coax being run forward towards 
the centre and supported on the crossarm and brought downward to the AZEL 
rotor.
Now does these different coax runs have any  effect on the performance 
forward gain or radiation  pattern ?

Just a few days ago I had a tough time on the new tower lifting the 2 beams 
with coax weight at the back and placing it on the rotator.
Hence if it does not matter much I plan to change the coax run towards the 
centre and bring to the crossarm holding the V and U cross yagis.

Looking forward to your valuable suggestions and knowledge.
