Universal Filter By-Pass Accessory

Band pass filters are a common, and popular accessory used by hams. Some hams have multiple filters which they swap out, depending on the band they want to operate on?

Multiple band-pass filter arrangements are offered from a few manufactures, but can be expensive, to the point of pricing the mono-band filter user out of the market.

There are a couple of frustrating problems with mono-band filters.

  • The principal one, is the requirement to take it out of line, if a different band/frequency is to be used.
  • The second, and maybe the most significant, is changing bands, and forgetting that the filter is still in line. Depending on the radio, this situation has the potential to cause serious problems, maybe even damage to the filter or radio or both?

I have searched to no avail, for a low-cost/reasonably priced product, that would permit the filter to be switched out of line when not in use? I have not found anything at any price that solves this problem! Is anyone aware of such a device/product – short of purchasing an expensive multi-band filter product, please contact this seller!

System Includes

  • The PROTEKTO system© is comprised of two coax jumpers, with connectors, available in two sizes: 6” & 12”.  These should provide enough length to accommodate most aftermarket Band-Pass filters. 
  • A [3’] control cable from the remote on/off switch, to the By-Pass unit; with an LED indicator to show when the filer is in-line. The [3’] ft. cable should be long enough to accommodate the remote location of the By-Pass unit.
  • The By-Pass unit is 1” W x 1” H x 3” L.
  • The control box is small enough to be conveniently placed next to the radio and/or operating position. 1” W x 1” H x 2” L.
  • A [10’] DC power cable with a standard 2.1mm plug, for connection to a 12 volt power source.
  • An optional DC power supply/Wall-Wort is available.
