![]() Okay, all. I rand a multi-band check on my s-meter. The results a (with the previous 80 meter test included. 80 meter +20 start S9 -18 db S8 -23 db S7 -26 db S6 -29 db S5 -32 db S4 -35 db S3 -37 db S2 -39 db S1 -41 db 40 meter +20 start S9 -18 db S8 -22 db S7 -25 db S6 -28 db S5 -31 db S4 -34 db S3 -36.5 db S2 -38.5 db S1 -41 db 30 meter +20 start S9 -19 db S8 -23 db S7 -27 db S6 -31 db S5 -34 db S4 -36 db S3 -39 db S2 -41 db S1 -43 db 20 meter +20 start S9 -19 db S8 -22 db S7 -26 db S6 -30 db S5 -34 db S3 -38 db S2 -41 db S1 -50 db There is no doubt that the readings are different, and significantly in some cases. I will give a calibration of the meter for each band that I do. Lesson learned here is that the meter should be calibrated to do this test, IMO. Yes, it is true that on any given band the readings are going to be relative to each other. But it is inevitable that questions will arise about the relative efficiency of my antennas by band, as both are multi-band antennas. Part 2 to follow soon....... -73 de Mike KB3EIA - |
