Nie, dziękuję Przekieruj mnie tamsingle_malt wrote:There is no need to philosophize here, all the following types of antennas are based on dipoles, only the type and geometric arrangement can be different, and the principles of work are different:Correction, these shielded antennas are of course the Yagi type, not dipole, as I wrote from momentum. You can of course philosophize whether Yagi is also not a dipole, but supported ...
single_malt wrote:I do not understand the statements that YAGi antennas do not work in the 800-2600MHz range (why not?), Because their specifications and signal measurements indicate that they work as well as possible.
single_malt wrote:I think that testing without a double Yagi directional antenna connected does not make much sense because we do not get any valuable information except which transmitters on the BTS are on and that the further BTS gives a weaker signal (physics).
single_malt wrote:In an open area, the higher the BTS frequency, the more important the directionality of the antennas.
single_malt wrote:It is therefore good to mount the antennas on the mast rotating in a pipe-in-pipe system, then precise rotation is very easy. Then block the outer pipe, but in an extremely strong wind, e.g. 150 km / h, the blockade will be released - it will protect the antennas.

TL;DR: Aggregating two LTE bands (e.g., 2600 + 1800 MHz) on a Huawei B535 can lift download speed from 30 Mb/s to 90 Mb/s “if signal and antenna match” [Elektroda, WarHawk480, post #18279118] “There is no one-size antenna for the B535” [Elektroda, matek451, post #18197795]
Why it matters: Correct band tests and a tuned MIMO antenna prevent costly, slow ‘electro-breakers’.
• Huawei B535 supports 2×2 MIMO and 2-band aggregation (max 40 MHz total bandwidth) [Huawei Spec]. • SMA-F connectors accept ≤ 10 m 50 Ω coax; each extra metre loses ≈ 0.2 dB at 1800 MHz [Coax Loss Chart]. • Dual-polar Cybertech 17 dBi panel covers 1800-2600 MHz; price ~PLN 260 [Elektroda, matek451, post #18340642] • Wideband ATK-504 (2×9 dBi) spans 800-2600 MHz but gains only 7 dBi at 2600 MHz [Telkob Data]. • Oversize Yagi across 800-2600 MHz loses > 4 dB on high bands—edge-case to avoid [Elektroda, matek451, post #18236762]
