TRI7 10/15/20 SF is the smallest of the Momobeam triband antennas that use separate feeds. Both 20 and 15 meters use full size elements with a reflector and driver configuration, while on 10 meters, the active elements are a reflector, driver and director configuration. TRI7 10/15/20 SF is perfect for multi transmitter stations. In fact, the solution of the separate feeds gives this antenna a great versatility. It can be used simultaneously by three different transmitters as if they were connected to three separate monoband antennas (use of BPF is necessary to protect your equipment). As a result, the space used on the towers is significantly optimized!
This antenna allows the station owner to move to a multi-operator category in a simple way. The advantages of this solution are:
1. Decreased number of installed antennas
2. Reduction of the surface exposed to the wind
3. Elimination of a DIPLEXER or TRIPLEXER – less complicated station
4. Easy to setup multi-antenna/multiband stacking if desired

Requires three coaxial cables
Requires a rotor for a medium/light load

*Wind survival is the maximum wind speed to which the antenna can be subjected without incurring permanent deformation (calculated in the absence of ice)

**The Momobeam RF Choke (standard product offering, rated at 3 KW) is made from high quality Teflon dielectric, double shielded, low loss coaxial cable with properly selected ferrite material that is sleeved over the cable that together, create a high impedance path for RF, providing high isolation between the antenna and coaxial feedline.

An SO-239 female connector is included for convenient attachment to the customer feedline and its PL-259 Male connector.

The 5 KW and 10 KW rated RF chokes (optional purchase) are made from the same materials except the coaxial cable is 10 mm diameter.

The 10KW version uses a 7/16 DIN style connector.
