You'd need an SWR Meter that's able to function in that range. Like I said earlier, generally manufacturer's will tune their antenna's for an SWR of 1.5 on an average power output. Problems with that arise when you start messing around with connecting external antenna's. Each connection that you make, through pigtails and such is going to add to the SWR, as well as to the db loss. As your SWR approaches 3.0 you're going to see your reception and transmission degrade.Originally Posted by PeppersGhost
Back in the CB days, it was a big deal to get the antenna's tuned up and get the SWR down to 1.1, of course you can never reach an SWR of 1:1 because that would mean you'd have a 100% efficient antenna, which just isn't possible.
I have a meter here that goes up to the 900mhz range that I could use to calculate SWR, but it isn't an SWR meter per sea. It will measure forward and reverse power and then you can calculate it from there. But I've never actually seen one myself that operates in the 2.4ghz range.
