Jako Posted July 21, 2018 Share Posted July 21, 2018 That antenna only provides a 2 dB amplification at 800 MHz. I 'd prefer this one: amazon.fr:That would give you at least 9 dB. (every 3 dB doubles the signal strength)Or this one: clickThat one even claims 20 dB, but I think that is a bit optimistic. Link to comment Share on other sites More sharing options...
Martin963 Posted July 22, 2018 Share Posted July 22, 2018 Blimey at that price you might just as well buy a Group C/D UHF TV aerial, or even a UHF log periodic, and experiment a bit to see which polarisation gives the best results at your location.Assuming of course you're certain that it's the 800 MHz band that's delivering your 4G.....Incidentally, as far as transmitter power is concerned, a 3 dB increase in power does indeed double the transmitted power (for example, a 3 dB increase on 120 kW gives you 240 kW). But when it comes to reception, you need 6 dB increased signal strength to get a doubling. All to do with whether you're talking power dBs or volt dBs.

Dave in the Aude Posted July 22, 2018 Author Share Posted July 22, 2018 Haha! I'm quite happy with my small flat panel antenna, mounted discreetly under the gutter, most people don't even notice it.At 20€ (thanks eBay) and giving me 20Mbps 40ms ping at 5kms from the mast, I'm very happy.All the best, Dave.

High frequency bands have more capacity but poor range and are only used in cities. Obviously you need two antenna's, so just one TV areal is not enough. You can always give it a try with two TV aerials, but giving them enough rotation so they end up at 90 degrees to each other would be a challenge as they are not designed to do that.
