Re: Buying Line6
Something marketed as "low loss coax" - like this:

Take a look at the horizontal and vertical beamwidth specs. It's quite similar to looking a speaker data sheets, often you can see polar specs etc. You'll see that the antennas with the most gain also tend to be the most directional. You don't really need something with a ton of gain for typical applications like we're talking about here. Pick something that's appropriate for a range of situations you'll encounter.
For that matter, for the price of these you could afford a couple different antennas to have some flexibility.
Here's a fairly general purpose omni with narrowish vertical pattern.

Here's an example of a small Panel type which is more directional:

There are indeed many options, but in some ways the speaker industry is no different. Choice is good.
