Sark 100 antenna analyzer test frequency

Thanks. I have this manual, maybe my issue with it wasn't fully understood. Look at the picture attached. The sark is showing the test frequency is 40.810 mhz. Connected to a frequency counter it is actually putting out 27.206 mhz. they should match. Right?
I'll have a measure of mine once I recharge the battery.
Havent used it in awhile.

Good question. I haven't used mine on a single frequency yet. I'm scanning different bands on the antennas I have. In fact I never actually calibrated mine. I attached a 50 ohm dummy load to see what the SARK100 said the ohms were. Then I measured the dummy load with my multimeter, and they were exactly the same. So I called it good.
I know my antenna system is spot on. When I check it @40.810 it’s 49 ohm but 27.205 is off the chart. I built the cal connectors and calibrated it when I first got it. But never figured out the test frequency discrepancy
How did you build the calibration loads? I would like to do this myself.I know my antenna system is spot on. When I check it @40.810 it’s 49 ohm but 27.205 is off the chart. I built the cal connectors and calibrated it when I first got it. But never figured out the test frequency discrepancy
PL259 each resistor value. Solder one lead on center pin and the other to the shield housing. I may or may not have one of them in my parts bin. If I can find one I’ll post a picture.
Does the wattage matter? I have some small resistors I could use, but they're only like quarter watt.
I would verify the tolerance of the resistors are spot on. If you have a dummy load it will work for the 50 ohm
