I had a ROTR100 installed with the TB-105 thrust bearing, but the mast snapped. A really wimpy mast and mount that was already there mounted on the eve. The antenna that fell was a Weingard HD8200U. The antenna boom broke too, but I think I managed to repair it. When it was up, I got really nice reception until the wind blew it down and snapped the mast. The rotator had to be replaced too.
I need some help in getting it re-installed and I'm working on it.
Anyway the side mount was changed to 2 pieces of Electro Gold (EG) strut that straddles an eve vent. The top strut is attached using all thread and is nice and solid. The lower strut fasteners are of the screw type into the 2 x 4.
This is the new plan: I have made out of slotted
strut, a 45 degree support with that has a 400 lb load forged eye bolt at about 1.5 foot and at 2 foot from the side. The other eyebolts are through the roof with turnbuckles. The 45 deg support is not installed yet. The mast is made from EMT tubing and attached to the strut using the standard strut clamps to do so. One of the necessary brackets cost me about $85 for one fitting. This one: http://www.superstrut.com/ps/fulltilt/index.cgi?part=AW219
This bracket is for the member that sticks out perpendicular to the side of the house. I used the standard 1-5/8 channel for perpendicular piece and for the 45 degree member, I used the 1/2 sized channel. There was an eve vent to deal with and I lucked out in terms of position, so that the anchor areas don't interfere with the mounting of the AW219. I used EG bolts too. I don't want to have to deal with rust stains on metal siding. The eyebolt mount was done somewhat unusual too. The bolts are about $15 USD each, not including the square washers. I think they are 3/8" diameter, SS and drop forged and about 8" long (not sure).
The problem I ran into is that the way in which you have to orient the Eagle Aspen is toward North. There is no way to get around that. North in my case is probably within 10 degrees away from the roof line. What this means is that there is no way to get three guy wires attached to the thrust bearing. The mast needs 3 guy wires and you cannot change the orientation, so I have 2 on the roof and will have one about 2 feet perpendicular to the side of the house.
The next problem that you will have is that the North TAB has to be cut off
. Normally, this rests on top of the main mast. I did on the last install, change the allthread to stainless steel. They need to be heated to be removed and re-locked with threadlocker. and I managed to change the mast clamps too, Parts such as ground strap, hose clamp to stud, ground braid and aluminum mast came from here: http://www.dxengineering.com/
The antenna clamps were changed to stainless as well. I think I needed a little more thread because I think I used two opposing clamps with double nuts. A ground strap was used around the rotor.
The antenna also has to clear a chimney. I have to use this side of the house because of a BIG tree, For now, I've been running a less than satisfactory solution on the other side of the eve.
So, it's not easy to get things to work out. The Thrust Bearing will work. I could not get dimensions for the life of me, so i just had to order it.
Not being able to arbitrarily position the rotor is a necessary evil.
There are about 8-10 locations for TV in the house from a Slingbox and at the time a VCR. There is a 36-52 db amplifier in the main distribution area and then there is the Winegard Mast mounted amp.
I did use a separate RG-6 for power and an RG-6 to a mast mounted Weingard AMP. The amp can't be powered from the ROTR100. The power injector for the AMP is in the attic. The RG-6 is copper clad steel for about 75' which isn't recommended. This drives four 4-way taps. There was a way to inject an NTSC signal on channel 4 and that's still in place. There is at least one location that needs to migrate from twinlead to RG-6 and one location that needs to get hooked up period. The holes are drilled and the wall box is mounted. I cannot receive some stations where the twinlead is. In that case, I use my laptop with the Slingbox which has the shortest signal path. If I want, I can use the laptop HDMI output and run it to the TV.
Plans down the road are to map the channel gains and figure out what I need to do and get a custom attenuator made to normalize the signal levels. I already have the meter to do the mapping.
At the initial time, I was thinking about using one of these tilt devices for the antenna http://www.atechfabrication.com/reception_solutions.htm
but at the time they were no longer available. It now looks like they are available. Not cheap.
There are two VHF stations that are 2edge signals and are 37.4 NM (db) and 28.4 db based on TV fool. Here is a snip from the TVFOOL output.

Do you guys have any idea what kind of improvement can be had using a tilt system?
And the final question:
Since the Eagle Aspen is a Deseq (sp?) kind of system, COULD:
1) An Eagle Aspen control box be modified to control a Satelite actuator such that when you selected a channel, both tilt and rotate would happen automagically?
or is there any other way to make them both happen at the same time?
I'm looking forward to what everyone has to say.
