A three and a quarter inch piece of fat wire or copper tube.

It doesn't matter that it's APCO-25 (Digital). Any antenna that's good for
the frequency you're monitoring will work fine.

well I have a few antennas that are for 25-1300 mhz and they don't work for
squat the telescoping antenna works better but im looking for a base that
will receive 800 better than the radio shack base antenna "I have one of
them"

The problem is most likely the cable you're using. Coax cable has a lot of
loss at 800MHz. Depending on what cable you're using, and how long it is,
you might do better using the supplied telescoping whip antenna, on the
scanner itself.

What are you using, and at what length?

the short piece of coax that im using now and for testing other antennas is
just RG8-X the gray kind its not cut in any wave length it was just a long
jumper I had, other wise I would use belden 9913 super flex in 100 ft when I
find a good antenna. Right now I have the telescoping antenna in the long
jumper zip tied to a lamp as a temporary location

I think you would loose about 99% of your signal, @ 800MHz, though 100' of
9913. You might want to consider a mast mounted preamp.

Say WHAT??

9913 has less than 4db loss at 800mhz.

That means less than 60% loss, NOT 99%!

While you loose about 60% of the signal, you gain much more than that by
getting an antenna outside and up in the air. The 4 db is not relally as
much as it seems . It just looks like a big loss on paper. Take a
flashlight and point it at a wall at one step back, then take another step
back and see how little the light on the wall changes. This is about 3db of
differance. Take another step back and this will be somewhere between 4 and
5 db, not 6.
