[TowerTalk] Short Top Section for Attic Installation

[Jon Zaimes, AA1K]

Hi Dave,
Back in the 1960's my best friend's dad was W3ANO in Allentown, PA. He had a mast going through the peak of the roof as you propose, with a TA33 or similar trapped tribander on it. No rotor though. The mast went through the ceiling on the 2nd floor and he had fashioned a brake of some sort and a steering wheel on the bottom of the mast in the hallway next to the radio room. He would reach up to  turn the steering wheel to adjust the beam heading, then lock it down!
You will need a rubber boot where the mast enters the roof to keep water out.
Rohn does have a couple of short top sections: https://www.3starinc.com/rohn_25g_antenna_rotor_and_bearing_accessory_shelf_r-bas25g or https://www.3starinc.com/rohn_25g_top_cap_thrust_bearing_plate_r-bpl25g
Maybe a bit pricey for your purposes. Any cut-off straight section with two accessory shelves would serve the same purpose.
I have a couple of used top sections with rotor plates in my stockpile if you are interested.
73/Jon
