Wireless Joint

That's a possibility, locking onto a different tower/band with higher-gain antennas. I can receive from other towers and bands as it is, but the lower signal quality with those makes comparison difficult.

Does improved signal strength increase DL during congestion throttling? Here's an example. With AT&T as my provider I find DL speeds reduced during peak times by about 40% compared to very early morning hours, given similar signal quality. So at 5AM DL averages 20mpbs and midday DL is about 12.

I ...

The optimum value for a LP antenna only gives at best 10.5dBi gain. The manufacturers values are way over inflated.

That web page is a little over my head; it seems that the standard enclosed LPDA is reported as 10.6 across manufactures, but the bigger LPDAs report higher gains. This got me ...

for me it was like 5 - 10 megs down on the 10MHz channel vs 20 - 25m down and depending on the time of day spikes up to 35m and even 50m early (pre 7 am) weekend mornings on the 20MHz channel.
That sounds like congestion on the 10mhz channel, 5 to 10 down with good signal stats. I've never clocked ...

3. Signal to noise ratio is everything. I've noticed this in other tests as well. There's a few reasons for this. (Improving signal strength is a good idea, but SNR is much much more important)

B. The more narrow the bandwith, the higher SNR one will have. Why is this? Because the less spectrum ...

See if you can find a 20MHz BW band, it makes a huge difference over 5 or even 10.

I'm not maximizing 10mhz at 15 mpbs DL, so would a 20Mhz band still improve the download speeds at the same signal quality?

I would be surprised if you can find an actual LP with a gain of over 10dB. A single ...

Have I maxed out my SINR?

My location is 22 miles from the serving tower, but at a 4000' higher elevation it's almost LOS. I can actually get signal with the 2 stock antennas on the router (Quectel EC-25AFFA modem), but the speeds are only about 4-6 mbps and not that reliable. I installed a single ...
