Which VHF Antenna

All

I bought an Icom VHF/DSC radio at the boat show this week which will be linked to my Garmin plotter but need some advice regards an antenna. My rib has never had one fitted.

I have trawled the threads/posts on Ribnet relevant to this subject and while there is plenty of advice and tips, a lot of the information seems to be based on preference and opinion.

So my question is:
Are there a number of excellent reliable antenna's to choose from with equal good performance?
Ive been looking at Saltys 'Metz' and the V-Tronix rib raider.

Also ideally I will mount the chosen antenna on the horizontal plate on top of the A-Frame for maximum transmission, but this raises the question of fitting the boat cover. Ive seen and read posts of ribbers mounting the antenna on the side of the A-Frame.
Does anybody have personal experience of reduced reception with this set-up?

Help

Ive had several vitonix rib raider type small aerials, 2 got bent in dry stack and I didnt find the reception all that great when they wern't bent. Finally went for it and have a 1.2m shakespeare aerial fitted on a mounting on top of A frame which you can fold back (to avoid dry stack issues) very pleased, reception is excellent.

shame your cover would get in the way as my current setup would be good.

rules of thumb

buy cheap aerial and expect poor reception
longer is better (VHF line of sight)
yes a frame may give some interference if mount aerial on side of it
higher and longer is ideal (you want aeriel mounted as high as possible)
quality connections to vhf set (some connectors are poor), try the gold type which you solder the inner core bit.
Quality VHF cable also

do some research on internet also helps.

Thanks for the reply Boris

All good advice. Will give the folding bracket some thought as not a fan of A-Frame side mounted antenna's for lack of height reasons.

Cheers

I've run the v-tropic type in the past, never had a problem in and around the solent, you also regularly hear transmissions from the other side of the channel which suggest the range is fairly good

We have a metz aerial from Salty John and its been brilliant, both transmit and receive. Whip can be removed in about 10 seconds with a 10mm spanner if your putting a cover on.

I run Procom MA2-1SC 156-162MHz 0dB S/Steel Whip Antennas on both my RIBs. Have been very pleased with their operation.
