Hi everyone,

I need some input on my setup. I live in the suburbs of a medium sized city in Germany, so running in EU_868. Node and antenna are mounted in my attic which is the 4th floor, so ~10m height. And as the title says it is a HeltecV3 with this Ziisor antenna.
I can get good connections in my area. However for reaching the city center nodes I need to bridge ~9km. I can receive plenty nodes from the city center but I don't manage to be heard. I specifically for this purpose upgraded from this to the Ziisor and while I do see some reception improvements, they are not that big. And I can see no benefit on the Tx side at all. I expected more and I wonder if I am doing something wrong? I am using this connector, could it be bad? Any other ideas?
