I use the tripod----------
Iggy, as you can see I use the tripod on the ground. From the photos you can see if the dish was mounted on the roof I would not have been able to get a signal in ALL CASES. Especially if you are in a lot of trees. The father north you go the more the dish is set at a lower angle to the ground. Also, I use the oval dish, not the 18" dish for two reasons. One it will have a three head LNB for more than one receiver hookup (ACTUALLY FOUR) if you use a receiver in the living room and one in the bedroom or hookup in the storage compartment or outside. Also the oval over the 18" dish will not lose the signal as easy in a heavy rainstorm. The oval has more receive surface than the 18" dish.
The first picture is in NOVA SCOTIA, backed into a place in the CG. I had to get a gap in the trees behind me for a signal. If it had been on the top/ back of the 5 VER, I would not have been able to get a signal.
The second picture, again is in NOVA SCOTIA in a CG full of trees, If it had been mounted on the roof, I would have been unable to get a signal.
The third picture is on BAR HARBOR in Maine. Again I was backed into a CG spot the if I had my dish mounted on the back ladder or roof, I would have been unable to get a signal.
You will be able to receive your local channels up to about 150-200 miles away from your home base, after that, no local channels because of "SPOT" channel receiving of local channels.
I also use tent pegs to prevent the tri-pod from being blown over (they are the large nail type)
Iggy, just keep in mind the above information for your use. I have even received a signal through a hole in the canopy of trees I was parked in. All the time the onlooker would be saying "You will never get a signal"
I am pretty persistent. I also use a signal meter that is used by PRO'S for dish set up.
