Well, what you really want to do it to "get out". I imagine the near field is directly proportional to the far field, in terms of "power" (whatever that really is), so a field-strength meter much closer to the antenna than the shack should give a good relative indication of output. So, if the T1, with 5W in, and tuned, causes a FS meter to say 18uV key down, and the ZM-2 under the same conditions makes it say 15uV, then I'd infer the T1 was 20% more efficient.
RMS volts at the tuner output ought to be measurable, also. The tuner that puts the highest P-P voltage at a consistent spot on the feedline should be the more efficient. Dan / WG4S / K2 #2456 <snip> This is my question on the T1 and every tuner I use. For 5 watts out of the transmitter, how much of that goes to the antenna when I use the T1 rather than the ZM-2, etc... That's what I want to know, but darned if I know how to make such measurements. </snip> _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
