real world range estimate?

RouterOS General

I have a project where i have access to a tower right on the gulf of mexico coast (in mexico) and i want to provide access to crew boats that only go out 15-20 miles. I was thinking this:

  • There is very very little interference or RF usage in this area, i have some ptp links and i’m almost the only person talking..


    I want to mount a large 2.4ghz 90 degree 17db. sector atop a 150ft. tower, with a 26db radio and MT box right next to it (1ft run a cable).

then mount on the crew boats @ ~25ft high - a 12db Omni also fed by a 26db radio and MT box right next to it.

the idea is as the crew boats roam in this 15-20 mile area they can get coverage..


Anyone have any input as to if this will work? thanks

EDIT: i ment to post this in the wireless form..:frowning:

This might work, though 20 miles across water is asking a lot. One thing you should consider is going with horizontal polarity antennas as you will probably have better luck - they are known to work better over water than vertical. You’ll be paying more for antennas but it might be worth it. You still might have issues due to the CPE side only being at 25 ft…not sure if you’ll make it beyond 10-15 miles. I’ ve never tried such a deployment, just relaying what I’ve read about “water links” over the last few years and other’s experiences. I’d love to hear how this goes for you if you do manage to try it.
