Fibreglass Ariel for Rib

I have just purchased an Icom M323 for my rib, 5m and now need to decide on the best ariel. I have no A frame and was thinking of a Fibreglass Ariel mounted to the Transom, maybe a Glomax or Shakespeare.

Speaking to a Yacht Chandlers near me, I was told that the fibreglass ones can snap on a rib in heavy weather, does anyone have any experience of this. Further, I was advised to purchase a regular stainless 1m ariel ( a V-tronix rib raider was recommended) and transom mount, as there would be no significant difference on range. Again any views on this?

My cruising area is the River Crouch and Blackwater, rarely more than 6 miles from land and I believe not that far from the Coastguard stations in case of an emergency call. Again any advise would be welcome

Thanks

Get yourself a 1m whip antenna and mount it on a pole, 1.5m or so is fine. This gives some degree of elevation, which translates to range, and a nice fat radiation pattern that keeps some portion of it pointing at the horizon as the boat rocks around. This is the best of all worlds.
A tall fibreglass antenna has a thin radiation pattern - more pizza than doughnut - and is susceptible to breakage/delamination. The USCG switched from fibreglass to Metz steel whips on their small, fast boats as a result of breakage costs.

Dont bother with the RibRaider they are a waste of time IMO and very limited range.

A decent 1Meter whip or fibreglass will be fine.

Yep, snapped 2 fibreglass ones at sea! Wasn't impressed with signal quality of the raider either. Now got a 1 m stainless whip on top of A frame. Good so far!!

Thank you for your replies everyone. I found SaltyJohns phone number via his website and he was very helpful as he explained the best way of installing the antenna and the options available. Even said he will email me some further details/drawing.

Great forum and very helpful, thanks

Following the advise/drawings from Salty John, I purchased everything I needed from him. Now all installed and working great. I would like to say a great service and would recommend to anyone wanting antenna advise or parts.
