The “Starpoint” combining filters are pre-set at our labs, at the frequencies required by the customer.
Even at 100% modulation, they assure a good separation for adjacent frequencies up to 1,3 MHz.
The multi-program models are designed in one modular mechanical structure which can house up to four identical band pass Coaxial Cavity filters, type M1F4.

87.5-108 MHz |
| RF output power |
250 W - 500 W - 1 KW |
| RF Connector output |
N - 7/16 - 7/8” EIA |
| Operating temperature |
-10°C ÷ +50°C |
| Overall dimensions (W x H x D) |
48,2 x 30,8 x 57,8 cm |
| Weight |

In these configurations, the output power of the filters are added inside a combiner to rigid lines which belongs to the same unit, and which can be adjusted at 2, 3, 4, 5, 6, 7, 8 Narrow band inputs by means of all easy operations.
On request, with the same technology, up to eight different transmitters can be combined to a common transmission antenna.
A directional coupler is assembled at the output of the combiner, which delivers two reflected and direct monitories at a preset level of -50 dB.
