All used at 1.5 : 1 match or better The match for each antenna was not listed, and I can only assume that they were different. Regardless, what was the forward power with each antenna, and why was that not listed? No need Sure there is a need was the antenna tuned for max field strength or lowest SWR. There is a difference you know even though Lancer doesn't know it. Why don't you explain why max field strength and lowest SWR don't occur at the same time? As you have stated that you know. Better yet why don't you tell me why they do occur then, prove how smart you think you are. LOL Go wash off assclown No, your the one that pointed it out..... No, I'm the one that pointed it out a long time ago. And there are several reasons why it happens, but the most significant is because nothing in a mobile installation is perfectly grounded. The RF ground in a vehicle is the vehicle itself, and at the frequency of interest (27 MHz), it rarely shows the nice low impedance needed for a good ground plane, or 1/4 wave resonance to work as a counterpoise. So your meter might show a perfect 1:1 match, but the meter will be wrong because it, too, is referenced to the same imperfect ground. The -only- way to be sure you are getting the most signal from your antenna is to actually measure the signal, and you do that with a field strength meter. You can see the difference for yourself by doing your own test. Assuming you don't have a dummy load for an antenna, you will see that the best match does not necessarily mean the best field strength. I thought this topic was already hashed out a long time ago..... No Frank, Neil said it he Sure there is a need was the antenna tuned for max field strength or lowest SWR. There is a difference you know even though Lancer doesn't know it. I wanted him to explain it too me, since he acted like he knew the answer and wanted to explain it too, since according to him, I didn't know it. Quit bailing him out, let him back his big mouth up. |
