[QUOTE="Vipersan, post: 829473, member: 325666"] Ok ..just braved the elements to nip outside and remove the plate ..so I can check Africable using a linear approach... Checked the pretuned channel in using both H & V .. The signals are very similar ..but fluctuate wildly from about 1db to 5 db.. I'm leaning more toward dual polarity now as this would sort of make sense..As the 2 signals ocasionally would arrive in phase or out of phase reative to each other ..thus adding of cancelling..to create an increase or decrease in signal.Such a thing isn't easy to visualise with circular polarisation..but sort of makes sense. By inserting the plate you'd be making a concious descision to accept or reject one or t'other..but presumably there _would_ still be some interaction in front of the plate ..or point of depolarisation. Time to ask someone more expert what the effects would be? CH ? ...anyone ? [/QUOTE]
