amishgenius Posted December 5, 2015 Report Share Posted December 5, 2015 (edited) So far the antenna is quite impressive. I never noticed how big the hole is below and close to the tower. Close customers have much better signal as compared to a regular sector with no downtilt, even on a tower that is only 140 ft. It is also very quiet. The gain is a bit lower than the ubiquiti sector. I was concerned that such a small antenna might not have quite the receive gain but it performs very well on receive as well as transmit. My furthest customer is 4 miles, with the closest one at several thousand feet. The antenna is very well built, maybe to the point of overkill. But its a very refreshing change from trying to make everything as light and cheap as possible. This has a few drawbacks as there are more bolts to hold things in place, but I'm not sure what I would do different. For the most part you can tighten everything except the mounting bolts on the ground...where you can easily get to everything, and leaving only the mounting bolts for on the tower. So not bad at all. I would attach some pictures, but seems like you can't with a new account Edited December 6, 2015 by amishgenius Quote Link to comment Share on other sites More sharing options...
Tasos Posted December 5, 2015 Report Share Posted December 5, 2015 Thanks for the feedback and we are glad the 30-degree horn antenna is working well for you. We are still working out the bugs on the forum, so please try again to post your pic. We would love to see it! Quote Link to comment Share on other sites More sharing options...

wirelessrudy Posted December 14, 2015 Report Share Posted December 14, 2015 Nice. Is your 30º not a bit down angled? I mean, the signal still is best in the centre so the most reach you get at the centre of the beam? To me it looks your centre hits the ground only some hundred meters away? Lifting the antenna might give you more reach while not loosing signal at short range since the antenna already has much more vertical coverage than any normal sector. I would lift it... I have similar antenna to reach clients at 5 km. I have the antenna horizontal fit. The centre is aligned towards a client at 5.3km. This is a SEXTANT and I have -57/-55 (Tx/Rx seen at AP that has a 31dBm radio) At the same time I have one client (SXT-lite) at 2km at least 100meters lower and 40 degrees out of the centre line. This client still has -49/-50 as signal (seen from AP). Due the difficult situation (AP has to 'overlook' some trees at 15 mtr in the direction of its centre line) and the presence of at least 26 (!) 5Ghz frequencies amongst at least 8 with signals better than -70 (and my tower has in total 9 5Ghz radio's) we tried several solutions. We tried a SXT-5HPacD SA (31dBm with 13dBi antenna), we tried a SXT-5HPacD (31dBm with 16dBi antenna), we tried a SEXTANT (30dBm with 18dBi antenna) and we tried a 30dBm NetMetal on a 19dBi Interline 60ª antenna. But whatever we tried, or we did loose too much signal at the distant unit, or we did not have enough coverage on the sides. And at the same time all they had more noise from other AP's. Now the 30ª Cone is fit with a rb922UAGS-5HPacD (031dBm) we have the best results and a very stable connection. Although the unit is a bit heavy to carry up in a tower, when the mast mount is fit the aligning and fixing can be done with one hand... The only minor comment I have is that the 3 horizontal pane fine adjustment bolts are a bit difficult to reach with an allen key if you are a bit in an ackward location!

saintofinternet Posted February 1, 2016 Report Share Posted February 1, 2016 hello, i have been told that this 30 degree device can be used for PTP links as well. i think a 30 degree beam would be far more wide for a PTP link. even for say 2 kms a wide beam will attract a lot of stray signal creating noise for the primary link. please advise.

Guest Mike Posted February 1, 2016 Report Share Posted February 1, 2016 Hello, you can use our 30 degree Symmetrical Sector antenna for PTP links if you like to. Symmetrical Sector Antennas do not have sidelobes so you will collect much less stray signals that you might think but do not forget that the beam is 30 degree wide and symmetrical in all direction. If you are looking for narrower radiation angle, you can used our new UltraDish™ antenna which is aimed to be used for PTP links and also features TwistPort™ connector.

saintofinternet Posted February 1, 2016 Report Share Posted February 1, 2016 unfortunately the new dish is still not stocked by the Indian distributor so was wondering what best could be use. anyways i was not comfortable with the 30 degree beamwidth for a pure PTP link :-) let's see what best can be done.

Guest Mike Posted February 1, 2016 Report Share Posted February 1, 2016 What is the distance for that PtP link? Quote Link to comment Share on other sites More sharing options...
saintofinternet Posted February 1, 2016 Report Share Posted February 1, 2016 2 kms at present and later might be shifted to another location which can make it around 15 kms. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted February 1, 2016 Report Share Posted February 1, 2016 The distance should not be a problem but you have to consider the interference from the other client inside the 30 degree sector. Also the gain for such a distance is quite high. For PtP you should used antenna with narrower beam angle. Quote Link to comment Share on other sites More sharing options...

airgon Posted April 30, 2016 Report Share Posted April 30, 2016 Anyone can help me to find what of these antennas are the best choise in this escenario, Vented tower 2 arrays of 3 120° Ubiquiti 5 Ghz sector maximum distance client at 4.5 K.M most clients are in 1.5-2 K.M area of each tower some tower have 8 AP same antenna Mostly Ubqitui Rocket M5 and Mikrotik Basebox 5Ghz Using UNIII Band.
