Hi - Include a picture looking at the building where the antenna is located. It may give us an idea
of what might be causing your antenna detuning.

I had some odd SWR readings and not sure why, the antenna is not located in an ideal location. I have it on my balcony 6 floors up below are the SWR readings both good and bad.?
40m at 7.049 the SWR was 1.8.1 which is great and I have no problem with the results.?
30m at 10.132 the SWR was 2.2.1 not great but it's the lowest I could get.?
20m at 14.049 the SWR was 11.7.1 and the SWR never moved from this reading and I found this very strange an not sure why?
17m 18.104 the SWR was 1.7.1 and then I moved to another band and when I returned to 17m and same frequency I was not able to turn back to 1.7.1 The SWR was 13.2.1 and never moved just like on 20m.
15m at 21.060 the SWR was 1.1.1 and I have no problem with that.?
10m at 28.035 I was not able to get the SWR below 6.4.1 it stayed at this SWR through out the whole tune process.?
Not sure why the SWR is behaving this way on 20m, 10m and then once good on 17m and then the same as 20m and 10m with a high SWR and not moving.?
