Diamond X50A

The VHF/UHF base station at W6IWI uses a Diamond Antenna X50A on a 10 foot mast. A plot of the 2 meter SWR as measured by the SARK-110 is shown at the right. This was measured in the shack, so it includes some SWR reduction due to transmission line loss. As shown, the minimum SWR is 1.42 at 147.860323 MHz.
