New Hamation Shack-LAN FilterMAX II Band Pass Filter System with removeable W3NQN Filters
These filters are the famous W3NQN filters designed for low insertion loss and low SWR across an entire band with emphasis placed on maximum rejection of second harmonic energy.
160M, 80M, 40M, 20M 15M and 10M. Filters for other bands can be replaced. A unique feature which allows quick repair of a blown filter and use of WARC bands filters too!
The filters can be selected via front panel knobs, via our Shack-LAN Ethernet based controls, or remotely by applying +12 for each individual band to the rear panel control connector. Or by our new 4 wire control interface which is the same control interface as the EightPak.
