Here is my layout for the trailer
If you look at the kitchen counter next to the Chair, thats where I ran mine. I found there is a hole in the counter that the Water tubes run up in. I was able to reach the bottom cover without touching anything from there. I ran a clothes hanger (wire) straightened down and with a drill attached poked it through the stiff board bottom material. It was easy then to snake it to my ladder from there.
Im using a Mirror mount for the Whip type antennas. I do have a 4BTV Im going to try and get up this weekend on our outing to see how it works.
I hope the ladder will hold it.
Anyone mounted a vertical on the ladder without issues or do you think its too much load on it ?
