I then put a MatchBox in-line between my Antenna and Transceiver and Adjust-It; and can still hear all 5 Radio Operators on a Frequency and now all 5 of them can hear me. To Me That Is Very Real Improved Performance from My Antenna and Transceiver that is a direct result of using the MatchBox between them. ~ RHF . increase the capture area of a poor antenna, etc. It will MASK that antennas' short-comings ... same as sweeping dirt under a rug (notice, another mechanical analogy to the above.) I guess, any possibly way it can be explained to you, will fail ... If you introduce an inductance to resonate the antenna, you introduce a loss, if you introduce a capacitance, the same ... LC or PI networks, commonly used in matchboxes, have notable losses. I have a 60ft longwire, mounted ~40 ft. in the air. Since it is only physically resonate on but a couple/few freqs, and, since I am not employing some form of matching on the antenna, and since the antenna does not, naturally, present a correct impedance to my feedline/rig, some form of lossy matching must be tolerated ... since the matchbox is located at my receiver, whatever feedlines I choose will also become a part of the "antenna." The ideal placement for a matchbox would be at the antenna, as everyone is and has been aware of for a long time, or should have been aware. As I stated, continue to state, and have no other choice than to state when worried about being correct--no matchbox will ever improve the performance of a poor antenna--all it can do is allow you to get maximum benefit of that poor performance. SNIP "all it can do is allow you to get maximum benefit of that poor performance" What the hell is this supposed to mean? My best guess is you can continue to wrong. -- Telamon Ventura, California |
