23cm 1240-1310MHz 300W Band-pass Filter for Transmit and Receive

23cm Band-Pass filter with a super low loss of just 0.16dB is equally suitable for transmitting after linear amplifiers up to 300W and before low noise preamplifiers to prevent overloading from out-of-band signals.  Low loss of filter is achieved with careful design and adjustment.

This filter is equally good for transmitting and receiving.
