Been there and done that too. I have not tried the Log Periodic but would like
to get a report on how it works, Sounds like it could be nice

I am very aware of the loss associated with coax, and you are absolutely
correct! I recall mounting a special antenna for the 800MHz band, several
years ago, using RG58/U. To make things worse, the run was about 75 feet.
End of story...usless!

Thanks for the info!

You are right, a good antenna can really improve things but just as
important,
some times more important, is a good quality coax. I would suggest at
least
9913 or better.

As for the antenna, it is hard to pick just the right one for everything
you
want to hear. You either have to compromise on gain to pick up wide band
performance or you have to pick a gain antenna on the band you are most
interested in and let the other signals be received as well as they can
be.

A lot of antennas are made with low quality materials and poor
construction
techniques. For all around (wide band) I like the Icom discone antenna it
has
the loaded whip for low band and does a fair job up to about 1200 MHz.
Being a
discone it has no gain but is wide band. Construction is good and I have
had
one up on the roof a number of years.

An antenna you should consider, if you live outside town or have signals
mostly in one direction you want to hear is the scanner beam. You can
mount it
fixed in a direction or put a rotor under it. I have found, it works quite
well. I am not impressed with the materials used in it but so far it has
survived the weather for 8 months without falling apart.

You can buy, or build a single band, gain antenna that should do a good
job on
a single band and will receive local stuff on the other bands. If you have
a
couple of these for different bands mounted you can switch back and forth
as
your scanning needs change, These will truly give you the best gain. Look
to
buy or build with something with at least 6 to 9 db of gain, mount it as
high
as you can, away from power lines and metal. They will do a good job.

As I mentioned before, the coax is very important, if you lose all the
signal
you gain by putting the antenna outside you end up with nothing better
than
you have except the time and cost. Use the best coax you can afford, 9913
or
better and keep it as short and direct as you can. Do not use adapters or
spitters unless you have to (the add a lot of loss) and make sure the coax
is
weather tight.
