Low Pass TVI filters For Sale:
Low Pass for your transmitter
Add one of these filters to your transmitter to help prevent
TVI or RFI.
All filters have an SO-239 connector for input and output,
and are designed for 52 ohm systems.
B & W model 425 (Also know as FL-10/1500) low pass filter
It cuts off just above 10 meters, and will handle 1500 Watts.
Maximum attenuation is at 52 MHz, with at least 70 db across
This is an older model that seems much heavier duty. It weighs
almost twice as much as the newer model, and looks like it
would take more power. It likely was made in the days that
plate modulated AM was the rule. Paper work included. $35
Johnson Nye Viking 250-20 Low Pass Filter
This is a 52 ohm cylindrical low pass filter with a cut off
frequency of 45 MHz and 75 db of attenuation.
It is rated to take 1000 Watts of AM, or 5000 Watts
PEP SSB. $35
Alinco ELP-60 D LX low pass filter
For 50 ohm systems, with up to 500 watts of power.
This one has an SO-239 on one end, and about a 2 foot
length of coax and PL-259 on the other end. $30
Clegg 372 Low Pass Filter
The label says "52 ohms, 53 MHz cutoff, 100 watts
Squires Sanders Inc, Millington, NJ".
There is a small adjustment hole in the side to adjust a
trimmer capacitor for best interference rejection.
This one is in very nice shape. It looks close to new. $25
Drake TV-100 Low Pass Filter
This filter can be used from 160 thru 10 meters at full
100 Watt power, and at slightly reduced power on 6
meters. This makes it ideal for the newer 160 thru 6
meter rigs. This one works fine and looks fine also.
Paper work included for $18.
Prices do not include shipping from Florida.
