Gday Everyone, Anyone here use a 4G sim compatible modem? I have a Huawei E5186 from Optus. http://www.optus.com.au/shop/broadband/mobilebroadband/e5186/router It's been fantastic. But I recently moved back into the hills of Melbourne and my speeds/signal strength is 1/3 of what it was. I use the modem to stream on twitch and I am dropping way to many frames for it to be view-able for the audience and is lagging me heavily. The modem has SMA ports for external or attachable antenna. Here are the specs of the inbuilt antenna. Here are the specs for its 4G/LTE Bands. I am going to try and boost my signal strength, in an attempt to get some stability and increase the speeds. We all know 4G is extremely sensitive. My new place is in the Hills so there are lots of giant gum trees, but surely something is better than the stock internal antenna. Here are some options I thought about. https://www.ebay.com.au/itm/49dBi-4...307619?hash=item2f0a7b2d63:g:iyoAAOSwOTVZpMhu https://www.ebay.com.au/itm/AU-4-9F...169936?hash=item1ed76b9190:g:OUgAAOSwCMtaVIV3 https://www.ebay.com.au/itm/HUAWEI-...886828?hash=item23994e15ec:g:aqoAAOSwaLdaeRND https://telcoantennas.com.au/site/telco-iot-2dbi-3g-4g-4gx-hinged-antenna-700-2700mhz Has anyone got any experience with this stuff? are the more expensive antenna worth it from a telecommunications shop? Or will an ebay special do the job? Also with specs, I know I need to have antenna that supports the frequencies of the modem but I have questions about the "gain" spec and "Radiation" spec? Is gain the signal multiplier? and Radiation the way it transmits and receives signal? ie. omni all directions? Also debating whether I just grab some attachable antenna, or go all out and buy and external unit and bolt it to the side of my house?
