Malby,
1. The Raymarine was originally fitted with the boat which is 10 years old so it's hardly cutting edge tech. I'll have to look up the model number as its the sort that has the unit installed under the dash and the large handset contains the screen/buttons etc. I doubt it would be superior to the Horizon 1700. The Horizon is a great little compact unit size wise and is solid with die cast cooling fins.
Edit: I have a Raymarine Ray240 model VHF
2. Glomex was also fitted to the boat - again 10 years old. I see the TMQ seems to stock/import them.
I am within 10 klm's of the coast in Mandurah approx 70klms south of Perth in WA. I can receive Mandurah VMR, Rockingham VMR and Fremantle VMR clear as a bell. To pickup repeater frequencies it was my understanding you need to log on to the repeater channels relevant to the VMR service in your area. I'm normally on Channel 16 when I receive the distances mentioned above so I don't think I would be picking up repeater frequencies.
3. I don't know anything about the Pacific antenna's - but $129 is pretty cheap if they are 6db antennas.
4. Whitworths have only recently started stocking the Standard Horizons. The staff actually asked me what they were like when I was purchasing. I actually was tossing up between the Icom and the SH units but ultimately decided on the SH.Both would be very good units. Again I deferred to the article by Practical Sailor.
Another reference.

Sorry Malby I didn't originally see your other questions.
I was going to get the Digital antenna through Boe Marine in the US as I had a number of other items ordered as well. It now turns out their carrier won't deliver them and a few other on-line web based stores shows they want an arm and a leg to deliver. Looks like I'm back to having what is locally available which is not a bad thing but don't really know what I'm buying performance wise. So far the options are:
The Pacific Longreach Classic 2.5M looks good (part P6051) which is a colinear 6db - price unknown.
The ZCG in similar spec is only 5.1db
The Glomex RA 1225 in 2.4M colinear 6db also looks good and has a RRP of $187.00. This is probably what is currently on my boat.
