TRI16 10/15/20 BT
is a superb performance tri-band yagi designed to be installed on large towers. The wide spacing between the elements around the boom-to-mast plate allows it to be installed on towers up to 180 cm / 70 inches per side. It uses sixteen (16) elements on an 11.6 m / 38 ft boom with: 4 element (20M) reflector, driver and two directors; 5 element (15M) reflector, driver and three directors; 7 element (10M) reflector, driver and five directors.
Requires only one coaxial cable. Requires a medium/heavy-duty rotor.
RF Choke: 3kW included

*Wind survival is the maximum wind speed the antenna can withstand without permanent deformation (calculated without ice)
**The Momobeam RF Choke (offered as standard, rated at 3 KW) is made with high-quality, double-shielded, low-loss Teflon dielectric coaxial cable with appropriately selected ferrite material that is coated on the cable, which together create a high-impedance path for RF, providing high isolation between the antenna and the coaxial feed line.
An SO-239 female connector is included for convenient connection to the customer's feed line and their PL-259 male connector.
The 5 KW and 10 KW rated RF coils (optional purchase) are made with the same materials, except that the coaxial cable has a diameter of 10 mm.
The 10KW version uses a DIN 7/16 style connector.
