Sure, but if he's installing a radio in a vehicle, this is a less than ideal situation if the transmission location is not always the same. You'd have to find a spot, get out and set up an antenna, then break it all down if you move again.
So why waste the time and money trying to use a POS 1/4 wave whip when acceptable SWR's aren't even achievable without a suitable ground plane, only to have at least 50% less performance?
Lots of assumptions here. A 1/4 wave antenna, when properly installed and tuned, is an excellent performer. Similarly, a 9' CB whip will get outstanding results on a waggy which has plenty of metal for a ground plane. Performance isn't only measured by length of antenna. Angle of radiation has a lot to do with it as well. But with only a 4 watt system, it doesn't play too big a role.
I'd probably compare it to you guys on 2 meters using a hand held radio with the factory rubber ducky antenna vs. sling shotting a dipole antenna in a tree or using a J-pole. Night and day to hit the repeater...especially in rough terrain. Now add heavy amounts of DX into his equation. 2 mile mobile to half assed base station will likely be challenging to say the least. So why not just do it right from the beginning if it cost the same (or similar) money?
The rubber duckies that come OEM on Ham HTs are crap. No argument there, but it's an apples to oranges comparison. A dipole would get a better signal out for sure, especially if up in a tree, but then it wouldn't be portable would it? At least not with a hassle every time you wanted to move. A vehicle-mounted whip (5/8 wave or even a 1/4 wave) would be a damn sight better than a duck and more convenient than a tree-strung dipole or j-pole. Heck even with a rubber duckie on my 5-watt handheld, I was able to hit my local repeater with solid copy from 50+ miles away. It's all about location and height above average terrain, with a spattering of propagation thrown in. Of course I was on top of Perry's Victory Memorial at a few hundred feet at the time...
As far as the mobile radio goes, also a no brainer. We still only have 4 watts to work with (legally anyway). Why not have better flexibility taking up less room?
I'm thinking we're in agreement here...right? A mobile CB takes up a LOT less room than a typical mobile radio. Flexibility = complexity in most cases. Something to consider.
As for the OP's concern:
ok what i am lookin for is a set up where i can keep the walkie-talkies i have but be able to talk to them with a radio in the jeep. I thought cbs ran off a different frequency range?
It depends on what kind of walkie talkies you're using. If they're FRS, then yes, they're on a different frequency band than CB. You can't get an FRS base radio with a detachable (replaceable or upgradeable) antenna. GMRS will use some of the same frequencies without theis limitation, but you must be licensed to use them. No test, just a fee to the FCC. Also, any sort of a repeater you might want to run really should be coordinated to prevent intereference to other users.
Murs is another option that's license free, in a portion of the 150-something MHz Business band. I think you can get a decent mobile rig but they're not as cheap as CBs.
Which frequency are the walkie talkies you're using?
