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.

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.

yha I know I am going to get some loss on the coax but its always better to
have a antenna on the outside on the roof and the coax is LMR 400 ultra flex
not belden opus I thought it was belden but there the same any ways
I still wanted to know if there was any good scanner base antennas out there
I have the coax taking care of now I just need a base antenna that was my
original question before coax came up

Doubling the distance will cause another 3dB of loss every time you
double(!) Very simple. A loss of 6dB will show one S-unit less on the
signal meter. And running 100' of RG213,AirComm+ and lowloss
TV-cable(75Ohm) to my antennas in the attic 6th floor is a GREAT
improvement in comparison to the same antennas 10' over ground in my 1st
floor appartment with less than 15' of cable to put the antenna outside
on the balcony.

^ ... I just need a base antenna ...

Start out by making a multi-element dipole antenna cut the legs of the dipole
according to the discussion in this group on vertical dipoles one pair for
each band that you want to listen to solder one end of one leg from each pair
together then solder those to the coax the final product will appear similar
to cat whiskers if you have any questions just ask here after you have used
this inexpensive antenna for a while you will know if you need to spend more
money on an expensive one

ok here is the real spes for Times LMR 400 ultra flex
