Ham Radio & Fixed Towers, TMM Series
US Tower’s latest design includes the compact TMM Series towers giving Hams in restricted areas an alternative. The TMM Series has a minimum retracted height of 11’4” (may vary, depending on rotor used) and a maximum height of 47’ including mast. At the tower’s retracted height, visual impact is reduced to a minimum and antenna servicing is made easier. Typically, the tower and antenna are below the roof line of your home when the tower is fully retracted.
The TMM Series towers are lightweight, freestanding crank-up towers that allow up to 20.7 sq. feet of antenna in 90 mph winds per TIA/EIA specifications. The TMM 433HD offers 31.8 sq. feet in 90 mph winds. These lightweight towers should provide many years of trouble-free service. All of our towers have a hot-dipped galvanized finish inside and out.
The TMM-433SS and 541SS have a 10” top section which will permit installation of the Yeasue G800 rotor inside the top section. Oversized rotors will prevent full retraction of your tower however they may be used if full retraction is not required. This restriction is dependent upon location of rotor plate. All TMM Series towers include a rotor plate, load actuated winch, and eight feet of 2” OD x .120” antenna mast.
The TMM-433SS will accept the MD-75 or MDP-750 motor drive accessory. The TMM-433HD and 541SS will accept the MD-75 or MDP-750 accessory motor drives. The MDP-750 motor drive accessory is compatible with both of our MCL-100 and RMC-1000 limit switch packages (see accessories).
