    In this webinar, we will look behind the scenes at what makes TwistPort connector unique - everything you ever wanted to know about TwistPort but were afraid to ask! A must-see for every WISP wanting to use, or already using our Horn antennas! NOTE: The TIME ZONE of the webinar is PST (Pacific Standard Time) - covering mainly Americas REGISTER HERE: https://attendee.gotowebinar.com/register/8472375213609235203
  2. Hi, it is compatible with all the RF elements HORN antennas combined with TPA-PAF TwistPort adaptor. It is also compatible with RF elements patch array sectors with the default bracket delivered in the LTU Rocket package. The older version of the TPA-PAF adaptor might need a small modification - plastic insert needs a few chips removed as shown HERE.
  3. The highlighted cable (in the attached picture) is the horizontal one, given that you mount it in the default position - with the panel (also circled in red on the bottom of the pic) facing down. The isolation between the ports is good enough to leave the vertical polarization cable disconnected (no need to connect it to a matched load or anything else).
  4. You're right, the Fresnel zone reflections are not a problem for circularly polarized setup. It is possible to make a TPA with circular polarization, but as of now we do not plan that. You guessed it right - it's all about the MOQ vs profitability when it comes to mass production.
  5. It is possible to make that, why do you need a circularly polarized antenna?
  6. Nice setup, thank you for sharing!

  8. Hi Francesco, to your questions: - the drain hole is there to protect the inside from condensed water. By sealing it with silicon properly, it will be IP66 rated - the hole is small enough. - yes the red plugs provide IP66 rating - more on this in the private message just sent Best regards

  10. The azimuth is not 'calculated' either, the calculator merely shows you the 'heading' of the antenna in the Multi CPE setup. The direction of the 'heading' is manual, and it is the clockwise angle from the North.
  11. The old one will have 'TPA-PAF-04_redu_1_v3' and the new one 'TPA-PAF-04_redu_1_v4' printed directly on the part.
  12. I see, the red dot connected to the dashed red line (with multi CPE setup) indicates the boresight direction of the AP antenna. The downtilt in this case is left up to the user, because with multiple CPEs there is no single downtilt that is optimal for all the CPEs at the same time.
  13. Yes, it will. You can either 3d print the plastic part (download files here) or remove a few pieces from the one you might have by your self - the parts you need to remove are highlighted here. People have easily done it by them selves with a few tools. The new version of TPA-PAF will have the plastic part that will fit the LTU Rocket as well.
  14. The downtilt is a parameter you have to change manually, but when you place the AP somewhere else, you always get the information about recommended downtilt, which you have to set manually (the change might often be very small because of the antenna main lobe properties, but be assured it recalculates with every position change) As for the rest of - thanks for the feedback, we'll look into it!

    Noise floor

    This Inside Wireless episode is about Noise floor, which represents the other side of the coin when talking about signal quality. Strength of the signal, or RSSI is important, but Noise floor is equally important, since the radio sees the signal quality through the SNR, or Signal to Noise ratio.
  19. What you suggest would not work - our horn antennas are designed for 5 GHz band, changing the TwistPort adaptor would not make them work in the band you mentioned because of the physics of the feeding waveguide which has cutoff frequency around 4.8 GHz. Any signal below 4.8 GHz will be reflected from the antenna port.
