hi folks.
I made up an antenna mast, 30ft of aluminum tube (which is mounted 5ft above my deck) right now the cable is inside the the aluminum tube.
the guy I bought the antennas from says the cable should be outside because the aluminum may cause RF signal to bounce around inside the tube causing interference.
I thought it was better inside for less wind resistance and to protect the cable.
at the top of the mast are two 8 bay channel masters pointing in different directions. right now they are one under the other but I intend to move the lower one down about 15 inches from the other (on advise from the retailer again)
so my questions are;
1) would you put the cable in the mast or outside?
2) are the antennas ok to be right under one another or would 15' between them make any difference?
I was thinking max height should be the goal?
and
3) is a smaller directional antenna better than the square 8 bay channel masters?
thanks for your help.
