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.

Very nice. Better than my HF meter.

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.

I bought it for my brother and he loved 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.

wonderful

Very responsive indication needles. And the two power settings with an off setting is convenient.

Accuracy in lower scale seems accurate with forward and reflected. However on high scale forward and reflected power highly inaccurate. On 20W scale with 15W in forward power was 15W out , while on 200W scale forward power only 10W. I do like the appearance and the OFF switch. The only problem was accuracy.

Very accurate.
