[CA] [CA11] RADAR and Reflectors

[CaptainM]

Hello,

I just purchased a used Trawler this past Summer. It came equipped with Raymarine RADAR mounted atop a short mast. I would like to mount a RADAR Reflector on the mast as well (probably a vertical "stick" type). If I mount the reflector next to the RADAR unit, will there be interference with either unit? This about the only place that the reflector will fit.
On my sailboat, I mounted a Tri-Lens reflector about midway up the mast. This worked quite well.
And...do I even need a Reflector? I do plan to cruise up and down the East Coast.
Thanks Much.
