[Ken Simpson, W8EK]

Low Pass TVI Filters For Sale:

A low pass TVI filter is added to the transmitter (inserted
in the coax line after the transmitter or transceiver) to
reduce harmonic interference.

Nye Viking Low Pass Filter Model 020-001
This filter is rated at 2000 watts, with over 65 db of
attenuation above 57 MHz. These are about $60 new;
this one is close to new for only $35.

Johnson 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. It has SO-239 connectors on each end. $30

Drake TV-3300-LP Low Pass Filter
This is a modern low pass filter to go between your transmitter
and antenna, and has been optimized to have more attenuation
in the 40 MHz region, where many TVs have their IF. It is good
for 1000 Watts "average" according to the manual, and has
over 80 db attenuation at 41 MHz. This one looks great, and
includes the paper work. $30

Drake TV-1000 Low Pass TVI filter
This is the low pass TVI filter that is in the copper case,
and may also be used on the low end of six meters, as well
as HF.
It is a 50 ohm filter and is good for 1000 W below 30 MHz,
and about 200 W up to 52 MHz.
This one works fine and looks good also.
With paper work for $30.

B & W model 426 low pass filter
B & W TVI filter, cuts off just above 10 meters,
and will handle 1500 Watts. SO-239 connector on each end.
This is an older model that seems much heavier duty. It weighs
almost twice as much as the newer models, and looks like it
would take more power. It likely was made in the days that
plate modulated AM was the rule. $28

B & W FL-10/1500 (Formerly known as model 425) low pass filter
B & W TVI filter, 50 ohm. It cuts off just above 10 meters,
and will handle 1500 Watts. SO-239 connector on each
end. This is the latest model B & W filter. It is in very nice
condition; it looks very close to new. With paper work $40.

Prices do not include shipping from Florida.

Thanks.
