I just took my mast down on my 311 a few months ago and re-did everything. I ended up just replacing the Shakespeare VHF antenna that was there so I could re-use the bracket, but switching to an ultrasonic, but wired, wind instrument. I also replaced the anchor light with an amazing one from LunaSea.
I documented it all at
