SWR meter for 2.4ghz systems


Does anyone have a link for a decent SWR meter for 2.4ghz systems or a multitude of frequency ranges ?

Cheers

Are you able to work on 100mw or 200mw ?

Thanx.

I have not tried. I will be getting a 100mw in a few weeks so will see how that compares against a 500

Thanx for your reply.
If you have time, please, tell me if it works with small power.

I have the model 801 SII. It is able to measure on a scale of 0-200 mw, 0-2 watt, 0-20 watt. It handles 900 to 2500 mhz.

bracky72,

Does the 801 SII work well at 2.4GHz? What's the minimum input level required for a valid SWR reading? Thanks.

Wow, perfect, the price is higher than S version but it's what I need.
Thanx.

Nestor - just checked and mine is the older/lesser S model and it does say min 500mw. I will try a 100 out of interest...

Daniel - When I put a claimed 500mw 2.4g tx on it It indicates approx 450mw so it's in the ballpark area. Good enough for antenna tuning and relative power output comparisons. Not seen anything else comparable for the price...

I have the Diawa SII as well. I have been messing with it for a few months now. The 2 Watt setting works great with our FPV transmitters. You need an external power supply to get the 200mW range. I find you can get a good SWR reading on the 2W setting as low as 200mW. I have not tried the 200mW setting as I don't have any transmitters that weak.

I am certain you can get a good reading out of the SII with power as low as 50mW. 10mW is probably too low for SWR.

All of my testing has been 1280 so far. This morning I'll work with 2.4 and see how it does.
