Here in downtown Montreal, it is very hard to pick up any satellites for Target mode. Was wondering if anyone had ever had success using giant antennas - a few of which you can find on Amazon, like this: https://www.amazon.ca/gp/product/B01MRN7Q96/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 Do they help at all? Am I risking any sort of damage?
I don't think those will help your GPS. They're for Wifi/2.4GHz. If you're trying to boost your Movi Controller or similar, then the antennae can help, or even better, look into a SunHans wifi signal booster. On the antenna, make sure you get the correct male or female for your transmitter or receiver. It's always opposite what I think it would be.
