That’s a relief , 9dbi will do me just fine thanx .The older tower I used to connect to was ~6km away (flat plane) using an XPOL-6 with 11dbi gain and I got ~70% signal strength, optimally they're super equipment. It also made sense why I got my 60-70mbps readings since this one was so far away compared to my new, very close but highly congested tower. With 9dbi I can assume 3-4km will still be great.
