TRI9 101520SF

TRI9 101520 SEPARATE FEED

$ 1,899.00

TRI 9 10-15-20 SF is our intermediate solution for tri-band antennas using separate feeds.
Each band features three elements with the reflector, driver and director configuration.

TRI9 10-15-20 SF is perfect for a growing contest station. In fact, the solution of separate feeds gives this antenna great versatility. It can be used simultaneously by three different operators as if they were three separate monoband antennas (use of BPF is necessary to protect your equipment). As a result, the space occupied on the towers is significantly optimized!

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 a rotor for medium load
Availability: 2 weeks
