TVI filters For Sale:

B & W Model 423
This filter has a cut of frequency of 55 MHz, so it is good for
use
on six meters, as well as the HF bands.  It has at least 50 db of
attenuation, and is rated for 100 W of power.  SO-239
connectors on each end. Very nice shape for $16

Ameco Model LN-2 low pass filter
It says it is designed for 50 to 72 ohm coax. This is a smaller
filter, good only for about 100 watts.  It could be used between
an exciter and amplifier, if desired.  SO-239 connector on
each end. Good shape.  $ 12

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.  I never saw one
like it before.  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.  This one is $30.

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.  $ 25

Prices do not include shipping from Florida.

Thanks.
