Only set up to have tower top plate at 27m (plus the 5' Rohn section). This is 4m between tower sections, rather than the normal 5m. I think this can be made repeatable by repositioning the top "micro"switch.
The top sonic and TRH will be on the 5' Rohn section. The beacon also will be on this section.
The sensor heights thus are 7m (top of fixed section), 15m (top of 3rd section), and 28m (on Rohn 5' section).
I would use two cell clamps directly attached to the "blocks" along the block's top edge to get it a bit higher (the TRH inlet still will be lower than the sonic).
Sonic booms will point (approximately) south (160 degrees – the same as the tower array), TRH booms will point approximately northeast (40 degrees). Because the TRH boom can't poke into the bed of the trailer, this sets the trailer orientation as the tongue needs to point approximately to the west (250 degrees).
We plan to use the omni Ubiquiti on this tower. We have a mount that will work with the special top-of-section clamps. Alternately, we could attach (u-bolt or hose clamp) to the top Rohn section. I actually think the reception may be better lower down due to the elevation angle response of the antenna – perhaps 11m or 19m?
Possible tt locations are red dots. I prefer the middle two, but driving access may be problematic.
