There are a few other things to take into question.

What frequency do you want to monitor?

The PD and FD I want to monitor isaround 45MHz. I'd like to monitor
the range of frequencies my scanner provides, also.

What is the elevation of the town?


Maybe 50 feet? I haven't moved to the area, yet.

78 miles is really pushing it, even with a beam antenna.


I've heard, however, people receiving from even 100 miles... I'd just
like to hear some other experiences.

I have a scantenna and it is a signal magnet!!! I have not had the
time to put it up on the roof yet. I have it mounted on the fence and
at best it is 6" high. I have copied VHF at 35 miles.

Ok, I need an antenna that performs equally well on VHF-lo and VHF-
hi... that's all I need. I've love to get the Scantenna, but I've
heard people say that it's performance is "so-so" on VHF lo. I need
great performance on both. A beam would probably be preferred.

Anyone have some resources where I can build my own antenna? I'm
wondering, however, if it would be better to purchase an antenna if I
need good performance on all of VHF-low (30-50Mhz) and VHF-hi
(148-174MHz).

forget about building it ....... it's too big and too complicated of
a job for what you want. better is to get a low band / high band TV
antenna ( channels 2 and up ) , the bigger the better and turn it
vertical for scanner use.. then get a suitable rotor and the
highest mast you can install , for any hope of success for the
distance you want to cover. a low noise stridsberg preamp and 50
ohm to 300 ohm balun are probably in the mix as well.

any serious multi element beam for 30 - 174 mhz and up is gonna be
a huge antenna . 12' to 16' long would be in the ball park for
all the freqs and distance you want . the antenna above is still
not large enough for perfect operation below 35 - 45 mhz or so .....
but more realistic than a dedicated 30 mhz 5 element beam.
( ie: 20' boom at 30 mhz )

just my thoughts on your question ....
