Identify this RNLI Vhf antenna ariel

Can anyone identify this RNLI Vhf antenna on right





Failing that are there any RNLI volunteers who can tell us what is on their stations RIB?

Many thanks

oh, reason I want to know?
Want a new antenna, toss up between metz, pacific or glomex and there seems to be too much bias in personal choice/experience in searching.

So taking a 'at the coalface' approach.

I'm 99% sure it's a Comrod, probably the AV51BI.

Performance is very good but where these really shine is in the build quality, these things are pretty much indestructable.

However, you could probably buy 8-10 Glomex's for the same price

Channel Ribs can give you a price on them, also on Pacific aerials which are very good for a reasonable price

I've got the AV60BI, a beautiful piece of engineering but probably overkill for most leisure boats.

Don't tell the mrs that though, just explain about how a vhf is such a vital piece of safety equipment and you should be good to go

She dont even know I've got the boat yet

I'm restoring it around a friends farm, once finished (and it doesnt need much) she should be o.k as she likes boats.

In fact she asked me the other day "what boat are you thinking of getting next?"

"oh, maybe a small yacht"

So it will either be or when I take her out for the day

Re: pm antenna price, no prob

Out of curiosity, what is that thick white antenna on the starboard side of the roll bar?

It looks like an active radar responder. Like a seame or echomax.

I would say that is an active radar reflector. ribs dont show up well on radar so a decent reflector is well worth fitting - active ones have an electrical connection to give them a boost to make the visible size of the boat bigger on radar without having a massive reflector fitted. my echomax looks like a pedal dustbin mounted on my nav frame!

yes but they now make an active one which is the same profile as the seame.

e.g. EchoMax Radar Reflectors -EchoMax Products

Sea-me Active Radar Reflector. Safety at Sea. Drastically Improves Radar Visibility. Amplifies Radar Signal. Automatic Ship Detection. Marine safety equipment and Marine electronics.

I notice they are now offering the X-band product reconditioned for £220 - that is starting to get into sensible price territory...

...just wish there was something sensible to stick on a 4m boat without an A-frame...
