High Sierra's New

Heavy Duty

40 Amp Noise Filter

This can help eliminate the noise! 

Here's another innovative product from High Sierra. We are making these noise filters at this time.  This is a real filter.  It is not simply a capacitor.  There is a power supply choke wound on an iron core (like a real choke) with two capacitors following the choke.  One cap is 1000 mfd.  In other words, it is much like a power supply filter after the rectifiers. 

We are manufacturing two versions.  One is rated at 20 amps ICAS and this one is 40 amps ICAS.  If you are running 100 watts SSB with the typical transceiver, the 20 amp version should be fine.  If however you are running 100 watts with a 100% duty cycle (like PSK31 or RTTY) this 40 amp version is the better choice.  The 40 amp filter is housed in a metalic case that is about 1.5 inches by 3 inches.  It has very head leads using #6 copper stranded wire with gold plated connectors. 

We found it to be an effective filter in mobile installations.  We also found that it helped with the noise generated by some switching power supplies.
