DAIWA CN-501V 140-525 MHz Cross-Needle SWR/Power Meter W/ SO239s

Mine is way off.. showing about half of the power compared to other meters. Also the SWR going into dummy loads shows high on UHF band. Multiple dummy loads that are rated 1.1:1 up to 1ghz are showing a swr reading of 3:1 while on VHF it shows 1.8:1. Took it to a friends house and mix/matched jumper cables, dummy loads, and radios.. just to rule out my equipment as the cause and confirmed it is in fact a bad meter. Maybe I just got a bad one but I wont buy this brand ever again.

The meter is very accurate, simple too use, and the power output/reflected power match up with another well known meter I have. A worthwhile investment if your looking for a great meter!

used to evaluate antenna swr and power output, does a great job, well built

Stuck needle when I got it. A swift good old tap on the top unstuck it. Works well. Measurements are OK from what I can tell.

Works good light is nice for reading in subdued light Only use it on a couple of different antennas and coax combinations but appears to give a good reading

wonderful

Very accurate.

This is my 1st personal swr/pwr meter having to borrow one a few times. This meter is very easy to read and appears to work very well. A word to the wise is to keep the watts setting at 200 watts until you VERIFY the output of your radio is under 20 watts. Then you can shift down to the 20w setting. Failure to do so may render your meter unworkable as my friend found out. Otherwise I am very satisfied with this product and would recommend it.

Similar results as Sev reported. No SWR (reflected power) indicated on 200 watt range but while on 20 watt range reflected power all over the map. Used my AEA analyzer to plot actual SWR vs. Frequency of my Comet dual band Base antenna then compared the results with my Bird wattmeter and finally this Daiwa. No surprise the AEA and Bird were very close while the Daiwa was much higher reflected on the 20 watt range. Even reversed the input and output coax to the Daiwa while using the Bird in line with a Bird 100 watt DL and 5 watts from my VHF transmitter. Forward power (measured on the Daiwa reflected scale) no where close and what was strange was the fwd power on the reflected scale was indicating lower than 5 watts (opposite of the indication when connected normally to my antenna - indicated higher reflected power). Did not even bother evaluating the UHF accuracy. No on off switch for the lamp either! Spend your $ elsewhere.
