Can anyone help please.
I am trying to tune my dipole aerial as per instructions from Europa to my krt-2
radio using a swm.
My initial reading were
Swm 1.7 on 118.00 frequency
5 on 127.00
2.6 on 136.9
I therefore started trimming 3 mm at a time off the ends of each copper tape.
This caused the lowest frequency swm reading to increase, the middle range to
fall
and the 136.9 also to fall.
The results for each 3mm trim were
118.00. 127.00. 136.9
1.4 5. 2.4
1.6. 4.2. 2.0
2. 4.0. 1.9
2.4. 3.0. 1.6
3.0. 2.6. 1.4
At this stage I lost my nerve and stopped trimming the aerial!
Europa instructions say middle range frequency should be lowest swm reading.
Can any of you out there advise on what I've done or indeed should do?
Best wishes to you all.
Graham.
