Firestik antenna length

Hey guys, need some advice regarding firestik antenna's. I plan to fit one using a dome mount on my spare tire mount but unsure on what length to run with.

I'm not after 20 mile range but looking for decent range for minimal height as I occasionally wheel where overhanging branches are an issue.

So what do you guys suggest would be a minimum height to run to get an acceptable range?

And will 18 feet of coax reach from the antenna to the radio running up the roll bar through to the windshield?

Any help would be appreciated.......

I got a three foot "no ground" mounted to the rear bumper - barely reaches the top of the roof, which most people will say the minimum is over the roofline...

however I have never had an issue where I have not been able to hear someone within a few miles and no problems on the trails...new england trails too.. with lots of trees !

I have a 3 footer on a spring no ground and works great with my Cobra 75 WX ST and it is above the roof line. Just remember most radios are line of site so if trees, hills, mountains and distance get involved then you may have trouble; also make sure you find someone with a SWR Meter to make sure its tuned (truck stops usually have radio shops).

Thanks guys, I should've pointed out that I'm posting from OS so if your thinking, why doesn't this fool get off his arse and get down to his local radio shop and have a look for himself, is because am cb's aren't that popular here and anything associated with them is getting harder to find. (Quality components that is ) One company (that I know of) sells the Firestik brand, but are 1700 kms away........

So I'll run the 3 footer mounted on the tire mount. Cool, that's sorted. I've searched around (on fleabay) and noticed numerous mounts that I could use, then I see different connections on the coax, damn! Too many options lol.

Since I'm purchasing from the US and having it shipped over to me, I dont want to be buying the wrong combo.

So I'm looking at the Firestik 11 FS3-B3 or the Firestik FL-3, opinions??

Would the coax with the fire ring be more resistant to corrosion ( eg salt water spray) than the standard screw fitting?
And if so, what base would I use between coax and spring?

The Firestick needs the spring mount to allow it to flex. Otherwise it will snap when making contact with trees. I run a Wilson 4' flexible antennae for this reason.

I have found that this setup from Cool Tech works well with a medium spring installed - http://www.cooltechllc.com/jeep/jk_gatemount.shtml I got my SWR readings <1 by turning the adjustment screw on the antenna all of the way down. The medium size spring I got at Radio Shack, and I have seen them in truck stops as well.

Not sure about the corrosion resistance, but the mount is aluminum, and the fire ring seems to have a good amount of protection, but I know that salt air penetrates everything.

There are multiple types of Firestik. The most popular I think is called the firestik II and needs a spring. There is another one that is 40% lighter, more flexible, and more top wound that is called the "FireFly". The name will have FL in it . Like FL3 or FL4. This one below is on a cooltech ultramount. I don't have one but it is the one I am planning on getting. From what www.rightchannelradios.com says it gets better reception than the wilson flex.
3' Length: 3 to 4 miles vs wilson 2 to 3
4' Length: 4 to 6 miles vs wilson 4 to 4

Thanks guys, had a good look around www.rightchannelradios.com so I'll get my gear from them. Shame the shipping through USPS will cost around 60 bucks.......Thanks once again
