TVI filters For Sale:
Drake TV-1000-LP
Low pass filter for the transmitter
This is the filter that may also be used on the low
end of six meters, as well as HF. It is good for 1000 W
below 30 MHz, and about 200 W up to 52 MHz. It is in
very nice shape, with the copper is still nice and shiny.
$ 35
E F Johnson low pass filter
52 ohms impedance, Catalog number 250-20. This is the
cylindrical filter, with an SO-239 connector on each end.
There is also a variable cap on each end, for precise adjustment
to cure your particular TVI problem. $30
B & W 425 "antique" low pass filter
I know most people are not going to think that a B & W 425
low pass filter is that old, but this one is. It appears that the
case is made of copper, or at least copper plated, and then
painted. There are just enough of the paint flakes coming
off to see the copper underneath. The weight of this filter
is about twice that of the more modern B & W 425 filters.
In case any one does not know, the 425 is rated to take full
legal power, and cuts off just above 10 meters. $30.
Drake TV-300-HP
High Pass filter for the TV. 300 ohm twin lead.
This filter is collectable, and is unused as best I can
determine. It is still in its original box, 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. $ 15
TVI filter, made by Communications Power, Inc in the USA.
This appears to be a bandpass filter for use on 10 (or 11)
meters, and is rated at 600 watts. It has provisions for tuning
the input and output for maximum TVI reduction. SO-239
connector on each end. $ 30
Prices do not include shipping from Florida.
Thanks.
