I apologize if this question has been asked/answered before but I did do a search on it and did not come right.

Ever since I got my OMNI antena, i keep jumping around BS though out the whole of JHB.

Is there any solution so that I can select the BS which utTracestar rates is the best?

If not, are they any ways I can position/angle my antena not to do this?

Your advice would be much appreciated.

Thanx
 
It's that omni as it's picking up all the towers in yours area, you need to get a directional antenna and focus it towards the best signal (tower) in your area.
 
What a waste of 400 bucks! How much are directional ones now?

I'm guessing I need this one?

This one looks similar to Michael's one isn't it?
 
If you got it from iBurst see if they'll take it back.

The antenna in the link you posted is what I think Who Is Michael is using, best let him confirm though.

That flat panel antenna that iBurst sells should also work but if posible rather get the yagi.

Maybe Poynting1 will advise you which is the best for you.
 
If iBurst won't take it back : snaffle one of your wife's largest Tupperware dishes, line the inside out with foil, drill a hole at the base for the omni antenna to go through and then rotate till you get a good signal... :D


Of course I won't be responsible for any loss of life, limb or any other damage that you may incur should your wife discovered what you've done with her fave dish... :D

Hi limnos

Yes, unfortunately iBurst and many others involved in the theory of the “iBurst System” still advise using omni antennas, however I am sure you have seen in many of my post and now with your own experience, that it is the worst type of antenna to use with a stationary UTD - when receiving strong signals from multiple towers, i.e. signal difference not greater than -15dB.

As MrH has suggested, the purchase of a directional antenna is the only practical (less fuss) solution. The antenna link you have pasted referring to the Yagi manufactured by Poynting (+/- R750) will solve your issue provided that the two towers are separated by more than a 45˚ angle – confirm this with maps from Google Earth – search your location and the locations of your towers by using Google Maps. (Or you could stack two Yagi's...)

Should the towers be separated by less than a 45˚ angle, it would be best to purchase an antenna with a narrower horizontal beamwidth. If you are not interested in solving the issue by yourself I would suggest you contact Graeme of Radiant Antennas, he has assisted some of my clients up north with successful installations and they have been impressed by the results.

Ideally you are in search of an antenna that has a high gain > 20 dB with a very narrow horizontal beamwidth < 15 ˚ that is suitable to use with MIMO technology and can withstand our local weather conditions and that is easy to deploy. – manufacturers take note please.

Let me know should you require additional information.

EDIT: The Librarian has given good advice - you could shield the omni from receiving multiple signals.

I know that Graeme of Radiant Antenna’s is experimenting with an iBurst (1792 MHz) feed that can be used with any off-the-shelf satellite dish, however this is impractical for use in the Cape Region due to our strong winds. (Have you ever watched DSTV while the South Easter is blowing?)

The Poynting (dipole antenna) grid would be more appropriate for use in the Cape Region, however they do not manufacture a feed for the iBurst frequency but RFShop in Australia does have a feed that is suitable for use with the grid and our local iBurst frequency.

Unfortunately RFShop is rather reluctant to sell the feed separately and the grid is of rather poor design.

The only other options are purchasing an antenna from Stelladoradus or an antenna from XA Associates, however the shipping costs are prohibitive.

Therefore the best option is to nudge our local manufactures to design high gain practical antennas for our needs.

Directional Antennas

RAY1800/17
1780-1800MHz, 17dBi Yagi Antenna for long range (out of zone) iBurst use.
http://www.radiant-antennas.com/commercial.php

This one really works, and has given me usable iBurst at -69 to -71db. It is far better than the iBurst flat panel which was ± -75db. Give them a call. Price is very good.

From Blairgowrie to Illovo base station:
Download 526kbps
Upload 223kbps
Quality of service 93%

Having just run UtTraceStar, I have been picking up BS 10 with -71db signal.
This is what I used to get from BS 27.
It appears that BS 27 is now BS 10.
BS 16 (Fredman Drive) & 17 (Hyde Park) are also visible at between -75 & -80db.

The load on BS 10 varies between 1 & 2.

When I was using an omni directional antenna, I could only connect to Randburg BS which was heavily overloaded and virtually unusable.
 
Gee gents.

Thanx for your solid advice. I'll see what I can do with those radiant antennas.

Thanx again for the help - much appreciated!
