Batboard

Hi, need some help with installing an antenna the one IM thinking of getting is An Antenex 107" long. the mast is 5' feet 1–1/4" diameter and IM going to use an Eaves Mount for the mast. I would like to know if this will be OK are do i need a smaller antenna one more thing can i use the same ground on my other antenna or do i need to run a new ground. any help would be very appreciated

thanks

Cmon man, what are you wanting to do? Are you transmitting? On both? One? How far apart horizontally and vertically? How high? How high other stuff around your antenna(s)? You on a mountain or in a hole?

Details, brutha.
