No antennas have ranges. Google some stuff like "marine vhf range" and you will learn all about it. Sorry to say you have the cheapest bottom end and I would not give it boat room.

Sorry, did not mean to be so blunt. However, I never understand why some folks spend so little on such an important safety item.

But surley the type of aerial you have onboard would depend upon your hunting grounds. Me in the Solent, with France only 60 miles away. I wouldn't be any further than about 30 miles from land at any time. A VHF handheld would almost do, certainly a fixed VHF with a cheap aerial mounted on an A frame would be OK in this circumstance.

Of course if you where venturing out from a more remote location then a better aerial might be needed, however I would start exploring satelite phones and EPIRBs as well, as most know that the range of a VHF transmission is line of sight and at 6' from Sea level the horizon is only about 3 miles away. So communication with a similar boat is 6 miles and you're relying upon coastgaurds and other radio stations having a much higher aerial than yours.

This is an interesting calculator, increasing the hight significantly doesn't have much effect on the range. A bit of an eye opener I think.

fitted the Vtronix the other day. will never be more than 1 1/2 or 2 miles from shore where i will be. On land the other day after fitting called up someone 8miles away and didn't work. it worked to someone 1 1/2 miles away. Was just wondering how far would it work to another boat at sea.have a handheld as well

I tried to call a CG station with a raider once. It was 10 miles away, line of sight and probably 250ft elevation. I could see them but I couldn't talk to them!
