Well, if all you really wanted to do was check your VHF SWR's there's a really neat trick you can do to use a CB SWR meter to do it. As mentioned I still have my SWR meter(s) from CB days One is a Micronta (Radio Shack) 3 dial (power/modulation/swr) unit and the other is a cheapie $5 special CB SWR meter. They really don***8217;t work all that well on VHF but there***8217;s a trick you can do that will net a reasonably accurate SWR reading. What you do is connect up the meter as usual, key the mike with the switch in the forward power position, then set the adjustment for full scale. Now, without touching anything, swap the coax connections so that the radio is connected to the ***8220;antenna***8221; side of the meter, and the antenna is connected to the ***8220;transciever***8221; side. The reading you'll then see on the meter will be very close to your real SWR's. The closer to 1:1 your SWR is, the more accurate it will be. It would be more accurate to have a real VHF/UHF SWR meter but they can cost $50-100. For a quick antenna check after an install or if you have doubts about your system the $5 CB meters work OK.
