On-Site Tunable Filters
This series of filters finds widespread use at co-located transmitter sites where unwanted carriers may make spectrum measurements difficult or impossible.
The VHF-SN (XXX) filters are a single, symmetrical field tunable notch filter. Notch depth typically runs -20dB or greater. A precision 10 turn piston cap allows the filter to be tuned over approximately 1 to 1.5 octaves. i.e. 80-200 MHz in the case of the VHF SN(140) filter.
Standard connector is F/F BNC. N, UHF and SMA are also available.
