TVI filters For Sale:
Low Pass filters for the transmitter:
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.
B & W FL-10/1500 (Also know 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. It is in very nice condition for $ 30.
B & W FL-10/100 low pass filter
Similar to FL-10/1500 above, except power rating is
only 100 Watts. Use this one after your rig, and before
your amplifier. Nice shape for $ 15.
B & W 415 low pass filter
This is a very heavy duty filter. It is almost twice the size of
most 1500 Watt low pass filters. It appears to be an older
filter, in a copper enclosure that has been painted at the
B & W Low Pass filter
Designed for 75 ohm systems. Very heavy duty. $30
Drake TV-5240-LP low pass filter
This number is correct; it is not a TV-5200. This filter is
different than the typical low pass filter. It has an SO-239
connector on each end, but instead of being long and skinny,
the enclosure is about 5 inches square. I think this is a
fairly old filter. It has brownish/gray paint over the copper
colored case. I have not been able to find any specs on
this filter. It does say "For use in 52 ohm line of transmitters
operating below 30 Mc." printed on it. $30
Drake TV-1000-LP Low pass filter
This is the 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. With paper work for $ 30
Drake TV-100-LP low pass filter
This is for lower power -- up to 100 watts.
It has the copper case. It is approaching antique status,
as I would guess it must be 30 years old, but still works
fine. Basically it is the same as the TV-1000-LP above,
but with one tenth of the power ratings. $ 15
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
Nye Viking Low Pass Filter Model 020-001
Eliminate the harmonics going out your feed line,
and reduce TVI. It is rated at 2000 watts, with
over 65 db of attenuation above 57 MHz.
This one is in very nice shape for $30.
Kenwood LF-30 A
This is Kenwood's low pass filter, with a cut off of
about 30 MHz, and more than 90 db of attenuation
between 90 and 300 MHz. It will handle 1000 watts,
and has an SO-239 connector on each end. It is in
extremely nice condition, with paper work for $35.
High Pass filter for the TV for 300 ohm twin lead.
This filter is collectable, and is unused as best I can
determine. It is still in its original box (not the newer
blister pack), with an "RLD" logo on it, and says
"NEW TV-300 HP High Pass Filter, Attenuates
0-52 MHz". A grounding strap is also attached.
Prices do not include shipping from Florida.
