Staying away from splitters. Thinking digital if it will not hamper my VHF. Both antenna will be mounted on a 23 COntender t-top. What kind of range to expect?

What does www.digitalantenna.com say? Seems to me it would be the dependent on the strength of the station your listening to.

The height of the receiving antenna, being a short one that is on a boat, will have no appreciable effect on the range, none at all. You are talking about FM signals in a frequency band from 88-108 Mhz, and in that frequency range what you get is basically line-of-sight with some ability to penetrate solid objects, but not all that much. So the range available is really primarily a function of antenna height here too, but with that little ability to penetrate - which is why you can receive FM signals for a short while after entering tunnels and before exiting them. Also, the commercial broadcast antennas are blessed with excellent grounding and the effect of that is that there is some, though not a lot, of tendency for those signals to follow the curvature of the earth. So the bottom line is this, with most broadcast antennas being a couple of hundred feet high, you tend to see ranges of as low as 30 miles, with more typical ranges being around 50 miles, and some hitting out there to about 75. What you see more often than not, and we see this in our cars mostly, is that stations have multiple broadcast antennas so give greater coverage of an area.

Dude,
Give it up already!! Your NOT going to get anything good offshore with ANY antenna.

Like I've said before, I've tried a TV antenna, FM antenna, VHF with splitter 10' up in the air, same without splitter.... all with almost the EXACTLY same results as using the little piece of wire antenna that came with the radio.

Nobody plays Bob Marley on the Radio anymore anyway?? Get a CD player!!

I think alot has to do with your local conditions and radio stations. In my expierience the type of ant. isn't going to make a huge difference. Check with some of your local guys to see where they lose the signals.
Up here, I lose most of the fm stations at about 20 miles off of Montauk and everything at 30. That will vary maybe ten miles depending on atmospheric conditions.
I have the CD but am considering satellite radio because I like to stay in touch with the world.

Bandit, Digital makes a 8' am/fm AND cellular antenna that matches their 8' VHF. Its the Digital 634. That way you don't compromise your VHF reception but help both the stereo and phone without having antennas all over the place. Let me know what you think.

Have you given serious consideration to XM? Might think about the cost of the Digital 4' compared to the XM unit.

Let me know if you have any questions- I own part of a couple of audio stores and am pretty well versed on them. You could get a permanent mount as well as a portable one and use the unit in the boat and cars as well.....

Just a thought- sorry for the off topic response!
Tom.
