,,, try to open the antenna panel, there may be something wrong inside or check the coaxial cable and the connections with the sma plugs...!!! ... could you show the inside of the antenna ... ??? !!!

I have tried many times to make a simulation at this antenna but I was never satisfied with its results. So I made a change to it, and I got some good results, especially with regard to the frequency bandwidth

I don't think this type of adaptation covers a high frequency band with an impedance of 50 Ohm...

,,, and impedance .... ??? ,,, why don't you give the dimensions...??? ,, and why not .. ??? batnew.cst ,,,or so..

Batwing antenna and offset dish...
-
,,, no, this. !!!
-
,,, put a Batwing antenna in the focus of the parabolic satellite dish ... !!!
-
,,,for which this antenna variant is also very good ... ???
-
,,, maybe it would be interesting to see these... https://www.lan23.ru/forum/node/340 https://deracahyono.wordpress.com/2011/02/26/isi-omni-built-up-hyperlink-15-dbi-review/ https://www.lan23.ru/forum/node/462?t=978

I think the best is the galvanized sheet ... !!!
-
I have only one question,,, for which frequency ... ??
-
,, or do it yourself...
-
,,, not good, very rudimentary, still studying ,, !!!
-
,,works very well...!!!
-
,,, it's stupid ... !!! ,,,, and mcneil's antenna is a fake...!!!!
-
,,, these would be the required details ... !!!
-
,,, yes, I think it could be with small corrections...
-
,,, for the 2m band...!!!
-
TD1205 it"s a high-end module for a faster and easier geolocation,but for what frequency ... ???
-
You should see that too...
