beryl must be edykated coz e writed:

Is there any advantages in having a 4kw as opposed to 2kw antenna
apart from the additional range. Which for me is a unwanted feature.

Will the higher powered unit detect targets in close proximity (less
than a mile) that would possibly have not been detected by the lower
powered unit or is everything just lost in sea clutter.

Has anyone had experience of changing to a more higher power antenna
and the possible advantages.

A bigger, i.e. greater diameter antenna will give a narrower band of
definition but the output power is primarily for range. Also can your "head"
unit operate with an alternate Radome?
