    Beam resolution

    Beam resolution displays antenna radiation beam width at -3db, -6dB or -12dB decrease from max (bore sight) gain.
  2. Very sane requirement but not easy to achieve.. That is all I can say at the moment
  3. jasne. urcite by som pockal s rozhodovanim na vyladenu a stabilnu verziu. pokial ide o beamforming, tam je z principu potreba viac anten /v zmysle viac priestorovo oddelenych vyzarovakov/. cize najjednoduchsie riesenie je pouzit dve 2x2 horn anteny a vyskusat to v praxi. Ona aj ta 4x4 antena originalnych vyrobcov (Cambium, mimosa) su vlastne dve patch array anteny pod jednym radomom, to nie je ziadne tajomstvo a v zasade ani ziadna raketova veda. U tohto typu anteny ale integraciou usetrite pomerne dost materialu (nakladov) a priestoru na stoziari. Integraciou dvoch hornov neusetrite takmer nic. Tak velmi zhruba a zjednodusene povedane..

  5. Zdravim, uz ste ePMP3000 aj otestovali v praxi alebo zatial sa len rozhodujete?
  6. https://rfelements.com/buy/ for spare parts, the easiest way is to contact Varia System
  7. Spare parts are regularly available with our Distributors. Master Distributors keep stock.
  8. We do not have dual slant and it is not convertible. AirFiber will work with whatever linear polarization you use.. H-V or dual slant, radio will figure it out.
  9. Shane - you need this TP-A: LINK Availability
  10. Jeromy, it is 160N @160km/h thanks for hint, we will update datasheet / website
  11. we do not have plans for such antennas in near future.
  12. The market for CPE add on brackets is fraction of what it was years ago, that is why you see less and less options on the market. UBNT (and other vendors) has products that have tilt already in package.
  13. Toro - this will answer your questions about distance, modulations, etc https://rfelements.com/calc/ Ultrahorn´s main strength is the performance in high noise environment due to it´s clean radiation pattern. If you are interested in user experience, check our RF elements English user group on Fb, there is recently nice deployment in discussion (posted by Reilly Flaherty).
  14. krajne polohy su plus a minus 12.5° Zvysok sa da pomerne jednoducho aproximovat. Pri vyzarovacej charakteristike tychto sektorovych anten by to musela byt skutocne specialna situacia, aby to zalezalo na jednom stupni tiltu anteny. stupnice byvaju na panelovych sektorkach - aj na nasich - kde je hlavny lalok extremne plochy (ma velmi nizky uhol vyzarovania v elevacnej rovine) a kde je 1° tiltu naozaj dolezity pre vysledok. Z rovnakeho dovodu udavaju vyrobcovia aj elektricky tilt, ak je to relevantne.
