![]() +Radio Shack DLX magmount .................... 0db +K-40 .................................................. ....... .8db +Radio Shack 4.5' center load .................. 1.4db +5' Firestik ................................................ 3db +6.5" Hustler top load ............................... 4db +108' Stainless Steel whip ........................ 4.5db +7' Firestik .................................................. . 5db Were these antennae used as the transmitting or receiving antennae? If transmitting antennae then what was the receiving antenna and receiving equiptment. Second unknown is the path loss between the transmiting antenna and the receiving antenna. Third item what was the gain(dBi) of the receiving antenna. Without the above data, the above results meaningless. Who's talking dbi ? I'm not. The reference was the RS deluxe mag mount. Referenced at 0db As I explained. The order of best to worst is accurate. Calibrating the results into db is as explained below. Meaningless? I don't think so. This test was done with an in sight very low power remote transmitter located about 200 yards away. A regular CB was used with low readings on the S-meter to give me a relative field strength. The exact S numbers were noted. Then next step was to calibrate the readings. The db calculation were computed after taking the same CB and exciting it with a variable power transmitter to see how the noted S-meter readings related to power output of the variable transmitter. |
