Antenna Tuner Anomalies: Flex 6700 running 1.0, Win 7: While listening on 40 meters just now I decided to try the ATU with my Tennadyne T-6 six element log periodic designed for 20 through 10 that also works with a clover leaf pattern on 6. Much to my surprise the ATU clicked a few times and reported "success." I was "dumbfounded". I increased power to about 30 or 40 watts and the Flex SWR meter continued to show very low SWR. Not trusting this at all I looked at my Collins directional wattmeter that revealed a pegged needle and 200 watts in both forward and reverse -- with maybe 40 watts actual power, a sign something is really amiss. My guess is the Flex is loading the coax somehow and the difference in position of the Flex compared to the Collins (there are a few feet of coax between the two) accounts for the this. In any case my gut tells me not to try actual operation. My concern is there may be instances where the ATU is misleading possibly with damaging results. So, experts, am I way over cautious and the 6700 ATU really can load up bedsprings or am I right not to try actually using the log periodic on 40?
