I like the 2800 for several reasons and have 2 of them. First, it's cheap. Like $100 and change cheap for a full featured radio. Second, it's tough. The whole radio is its own heat sink. Third, it has a large display and is very uncluttered and easy to read. Forth, the memory system is fairly logical and easy to program even without the software.-I was programming the Moab area repeaters while driving with Beno from Valley of the Gods, and that included alpha numeric tags. Fifth, it is fairly high powered for a mobile.
What it isn't, is an advanced radio. It's single band, and the "dual watch" is hard to use. For a trail radio it is nearly ideal. For a first radio, it's nearly ideal.
It also seems like 99.9% of radio coms are on 2m, but it would be really nice to have a dual interface radio like the 8800. Leave your base simplex on one side, and set up a local repeater on the other side. This has been very handy on trips into Death Valley, Rubicon etc. Interestingly both sides of the radio are set to 2m band in most cases. That's where the action is for mobile use. The 8800 is roughly 3 times the price of a 2800 but
is a better radio for an advanced user.
Regarding the sound thing-I've listened to a lot of 2800s and don't notice it but some do. It has to do with a dust shield over the microphone pick up inside the mic. Some people on the radio forums take it out, but they don't operate in the dust/sand/wet conditions that 4 wheelers do. I'd leave it, and have your friend talk to you on your radio and see what you think. Not really a big deal in my book.
Antennas-if you have a single band radio, you can use a single band antenna. (Duh, right?

) First choice there is a simple whip antenna like a Larsen 150. For dual band use, the SBB-1 mentioned by Tom works surprisingly well for such a small unit, and it had crazy good SWR out of the box, like 1:1.2. It's not as good at distance, but it is good enough for most uses. In my truck at any given time I have 3 antennas and use what seems best at the time, but the strongest argument for sticking with a single band radio, is the excellent and durable Larsen 150 series whip antennas.
In the end, antennas are the most important of your radio components, and one that doesn't get damaged on the trail is essential for 4x4 usage. So, choose wisely, and remember that getting out to constantly fold and unfold an antenna will make you crazy.
