I've purchased a Barrett 250. Am now wondering about aerials. A simple steel (metal) aerial has been recommended and of course if the cheapest. Would this be ok? Should I get one that can be folded in half or doesn't that matter. Is nylon better?

What you need is a tapped whip.
Have a look at ebay item No. 300151088337
You will also need a base for the antenna ebay item No. 300151992278
Usual disclaimers, etc etc.
The tapped whip and base will be your best option, but make sure that the antenna has the frequencies that you are most likely to use. (most important)

NO NO NO
You will HAVE to get a proper HF aerial, either an autotune, or a multitap with the right frequencies.

Thinking about it, The 250 probably wont run an autotune so you will have to go a multitap
I bought
mine on ebay with a spring base, fully recondition (looked new) with a near new spring base $275

There you go, I just assumed that the 250 didn't have the credentials, thanks Dave for setting that right

You will need a proper antenna to use with your Barrett, I was trying to find a website link for you , one place had them for $350.00, I paid $275 for a new at Terlins in
Perth, I think it would be a good idea to check out
VKS-737 Website,and do a search for Tapped HF Antennas for VKS 737.

I use a "famparc" tapped whip which works extremely
well.They are available for $130 dollars with all the VKS channels on them.
Just do a search on famparc and you will find out more info.

If you buy a tapped whip, make sure you know which organisation you want to join beforehand so you buy the whip to suit.

You will find that an autotune aerial will set you back as much money as the set (about $1500+ I believe).
Tapped whip with at least 8022 and 5455 for VKS is obviously cheaper.
Third option is to buy (or make) a SuperRod aerial, as sold at Electric Bug in
Adelaide. Its a 9metre (yep its huge) fibreglass or graphite fishing rod that simply folds down to one metre in length. It has a wire up the middle, which is about 8.9metres, which is the correct length for 8022MHz. The wire hooks up to the coax centre wire, and the coax goes back to the PL259 connector on your set, and the coax sheath is
well earthed to the body of your vehicle. I've used it as both an emergency aerial by itself, but you can also run it through an autotune. Takes less than a minute to set up. Given the huge size, it outperforms all other vehicle aerials - base stations almost always receive me as a 5x5. Used to cost just under $300 from Electric Bug.

The autotune aerials are great if you are swapping channels a lot but if you just want it for emergency use then the simple tapped aerial or even the wire up a tree approach is good. In fact you need this even with an autotune since Mr Murphy will make sure the sophisticated autotune will not work when your emergency happens.

Good point about the autotune - one rollover and its gone.
