Paul,
This particular antenna can have the wire go down through the base or out the side of the base. I'd prefer down through it. Yes, it does come with a 12v signal booster. The local "big boy" RV dealer/service outfit carries various Wineguard antennas and would probably have no problem with installing it for me if necessary. It's also cheaper than Camping World's - and no shipping!
I'll have to check with them with this.
Aaron,
Thanks for the comments. I'll definitely try to find out if there is any reinforcement before I do anything. I would think it would make sense if it did - since they marked the spot for the purpose.
Gene,
I understand the limitations of the omnis, but cost and roof space does have a bearing on what can go up there. It's just a little 1350. And, I'd rather not go as cheap and ugly as a wire coat hangar. <G> The one I linked to is a Wineguard, so I'm confident that it is one of the best of its type.
Thanks for all your advice. It's appreciated very much. I'll probably be in the research stage for a period, so feel free to throw more at me as appropriate. In the meantime, I'm going to be trying to find out about the marked/recommended mounting spot.
