Get a capacity cap on top. It will double the performance eliminating loss increasing rf out.
Ia it possibls t use Atas25 without nanov or Tuner?what ll b like
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
How about on 10 meters band without tuner ? How was your experiences on 27-28mhz sir ?Thx for your vid ,and your reply,73
@@mook4314 The ATAS-25 can be easily adjusted to effectively cover 27-28mhz without a tuner. Thx, 73
