radar antenna

I am replacing my old style radar with a new LCD one.
I use it primarily as a ship watch aid say 6 mile range. I already have an adjustable bracket aft that allows it to kept hoizontal. However this is about 10 ft above water. Should I put it up the mast say 25 ft from the water line?
I use this when crossing oceans primarily.
Any answers?
Thanks
Lawrie

While having the radar 25' above the water line, rather than 10' will give you a bit more range, it may also cause the radar to miss things that are relatively close to your boat, when they are more of a danger than when they are further from you boat.

Radar is setup to work over a certain angle of coverage, from the horizontal, assuming the radar is mounted level. The higher up it is, the further the range...but it can also miss things quite near the boat, as the higher up the mast it is, the larger the blind spot surrounding the boat.

I would personally prefer to have a bit less range, and be able to track items that are spotted all the way to the boat, rather than a bit more range, and then have to guess when the items are near the boat.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
