In my opinion, a 5/8 vertical should be set up to be a complete

Obviously, OCF antennas must set you off also.

Yes, they are certainly counter-intuitive ... there is form and
beauty in symmetry alright.

....and how about OFC antennas ?

Surprisingly functional? An ugly duckling?

Hi,

I have a Uniden 996 scanner and would really like to pick up some marine
traffic from Boston Harbor.
Live about 20 miles due west of the harbor.

Have a Scantenna antenna which I think is "pretty good". It's up in my
attic.

It's omni directional, and broadband over the typical scanner ranges
(supposedly).

I can often pick up coast guard conversations, but very rarely (but
ooccassionally) ship traffic.

Do you think a dedicated, very directional, and tuned to the marine
freq's would help, or am I just too far away ?

Any thoughts on, or antenna suggestions would be most appreciated.
No idea what to buy, if you feel it's worth a try ?

Very interested in the AIS data being transmitted by ships at around 162
MHz, as well as general marine stuff.

BTW: really surprised that I hear the CG at all. I would have thought
that their antennas would be "focused" out to sea, with any propagation
going the other way (towards me) minimized to maximize the effectiveness
of their radiated power in the direction that it's needed.

Thoughts ?

Thanks,
Bob

Hi Bob

Do you want to try building your own antenna? If so, I'd think a simple
antenna like a J-pole ( http://www.hamuniverse.com/jpole.html ) would be
worth trying.

Yes it is worth trying. I can pick a telemetry transmitter nearly 30 miles
away that only puts out about 5 watts on just above 400Mhz. There are 2
transmitters there and I can only pick up one .The one I cant pick up has
its antenna at about 20ft above the ground , the other is a 50 ft. Just an
example of what a difference heigth makes.
