As pointed out (more diplomatically) by SeaSkills - better to assume that even the best fixed
VHF will not give you ship to shore at that range. Not intending to sound rude here, but if you're even thinking about being out there (30Nms) then you probably should be upgrading your radio skillset first - not your radio. There is a great one day course being run all over the country - easy and costs about €80-100.
Having said all that... if you should find any wee parcels bobbing about out there, snag one for me, I'm feeling a bit low today
