    Get a capacity cap on top. It will double the performance eliminating loss increasing rf out.

      Yes it is possible. However, you will need some method to determine when the antenna is matched. One method I have used is to turn up the volume and adjust the antenna for the loudest background noise. That will get you close to where you need to be. From there you can place the rig in a constant carrier mode, preferably on low power, and key the rig while observing the SWR meter on the rig. If the SWR is high you can screw the antenna up or down a bit until you get below a 2.0 SWR. Thanks for watching. 73
