I also think that's the case. How can I find out if there are any other towers I can point the antenna to. I did a 360 but only connected to one tower. I have 2 weeks before I can return the antenna... at this point the antenna doesn't help at all
You need to drive around and inspect Towers. See if Telkom does have any presence.
The you need to make yourself mobile, meaning router and a DC/AC convertor(12Vdc to 220VAC). Unit plugs into cigarette lighter of car.
Then you power up your modem and check how may bars you could see on modem. If you see 5 bars you ok.
In my area there are 3 towers. Only at one tower I could get 5 bars. I think I'm allocated to this tower.
Don't think I get throttled.
