External antenna discussions

broadone said:
And out of the antenna listed in that url, which one do you recommend is the best?

And must one get an adapter cable as well - looks like it.

One other question - it says to point the antenna in the direction of the tower. If one doesn't know the direction of the tower I take it one should just try different directions to see which gives the best signal?

And I see that on one of their reviews a guy said he just put the antenna on his desk and that worked.

Cheers.

Good day broadone

Please can you PM me you details and address.
will see what towers are in your area.
To see what better option could be.

Some test results.
1820 with soldered connector for the external antenna.
Antenna 11dB from UniDirect
Antenna at 1m elevation - speed 8-10M
Antenna at 2m - 4-5M
Antenna at 4m - 12-14M (1st floor balcony)
Antenna at 6m - 4-5M
Signal level all time>-51dB
All results is very stable.
Antenna moved at any level +/- 2m horisontally - no changes

hi all

i am back with some results. after installing the high gain antenna i can CONFIRM that it definately DOES work :-)

i had a previous RSSI of around -97. after installing and pointing the antenna North towards a tower i could see closeby, it dropped down to -83. i then carried on playing around and i could see a tower South East of my position but around 10km away or so. I am now pointing it there and getting, wait for it, -65 :-) you dont know how happy i am now.

my previous speedtest results were unspeakable, (all sub 1Mbps) but did have times where i had 10Mbps. if you guys do want better signal you definately need to buy this antenna as you can see from the speed test results i'm posting. i'm averaging 10Mbps everytime and i had 1 peak at 16Mbps :-) which i unfortunately forgot to copy.

let me know if you need any details.

BTW, i use my modem connected to a Netgear MBRN3000 router so we can have wireless access throughout the house. i found that if the modem is plugged directly into the usb port of the pc and MDMA is used then my RSSI goes to -69 as opposed to the -65 i get plugged into the router. strange. i have had the router/modem plugged in and online now since yesterday morning and havent had a single dropped connection.

latest test 15:15 3-7-11 15 Mbps http://www.speedtest.net/result/1369166607.png

sorry to keep editing, 19,75 Mbps :-) go go power rangers :-) lol.. http://www.speedtest.net/result/1369170518.png

17.83Mbps http://www.speedtest.net/result/1369172229.png

Damn have you burnt a hole in the wall yet with those speeds??? Vodacon must be crying!
 
Using 21 element LA-PD aerial (designed for 1800MHz) mounted on a 1 metre pole about 4 metres off the ground with a Huawei E1820 modem plugged into TP-Link MR3220 router. The aerial uses an inductive coupler and is right at the end of the device. Aerial is aimed exactly at a CellC transmitter close to the Total Service Station in Diep River, Cape Town. Chose this location after 3 weeks fiddling and measuring. Now getting between 1.9 and 5.0 mb.sec, the average being 3 mb/sec. The signal strength varies between 55% and 78% but the download speed does not correspond to this at all. I also found that 900MHz gives consistently better results than 2100MHz, which is different from someone else's experience. 3mb/sec isn't marvellous, so I awaiting some inspiration to do more tweaking to get it up to 8mb/sec.

I took the modem to the Wynberg Boys' Junior School, and sitting in the staff room with the modem lying on the table, got 7.8mb/sec (at about 20h00 one evening at a Computer Club meeting)

Sent you my details twice and you don't provide any useful info, except to say cell tower locations are not given out. How are we supposed to help ourselves when CellC is so secretive?
 
Antenna + E1752

Hi there, I bought an Omni directional antenna (Poynting) that came with a 10m cable and the inductive coupler that goes around my Huawei E1752 (white Cell C stick).

The antenna doesn't seem to have an effect on my signal. I decided to open one of my modems to try and see where the antenna sits on the modem in order to put the inductive coupler on the correct place...

It seems like the modem might have 2 antennas and a connector for an external:
http://mybroadband.co.za/vb/attachment.php?attachmentid=29820&d=1353566791

What would be the optimal way to connect the inductive coupler? Would the external antenna connection be more affective and where can one buy one of these small connectors?


Any advice would be appreciated. Many thanks!

Do you have a pigtail or an inductive coupler?

If you have an inductive coupler, put it at the end of the modem (away from the USB plug).
I get best results on an E1820 by not even pushing the inductive coupler all the way onto the modem.

It will be a waste of money buying a pigtail as the E1752 does not have an external antenna connector.
If you need to overcome the losses of the inductive coupler, you can try cutting off the SMA connector from the antenna cable and soldering the cable directly to the modem.

See here:

Yeah sorry its the Inductive coupler. Thanks, will have a look, not to sure if Ill be able to solder the wires on.

I thought the connector on my photo (smallest red circle) might be for an external antenna, any idea what that is for?

I looks like the antenna currently has no effect at all. They gave me a 10 meter cable, how big of a difference would a shorter cable make?

One of the guys at Poynting told me that's a test point.

Shortening the cable would reduce the losses by a couple of dB, but I have found the gain in increasing the height of the antenna far outweighs the losses in the cable length.
 
Which high-gain antenna should I buy?

Hi Guys

There are currently 2 high-gain 11dbi 3g antennas on the market.

One is from Poynting:

http://www.poyntingdirect.co.za/pLP...cellphones-and-routers-include-7-m-cable.aspx

and the other is from Uniterm:

http://www.dbg.co.za/product_info.php?cPath=32_38&products_id=662

Any idea which one is better? They both look like they do the same thing, and both offer 11dbi gain, but why is the one from Poynting over double the price?

The one from Poynting looks like it covers a bigger range of frequencies, but unless I'm mistaken the one from Uniterm should cover all frequencies used by Cell C, MTN and Vodacom.

Any ideas?
 
Because Poynting are expensive... They seem to think that because they're a local manufacturer, they can charge double the price.

Haha, yes I gathered from their prices. Any technical reason why the one from Uniterm wouldn't work as well as the one from Poynting?
 
From what I can recall of the ZA cell allocations, it looks like it will work fine.
Give the Uniterm guys a call. They're very helpful.

I have a antenna similar to this one: http://www.poyntingdirect.co.za/pK-YAGI-NEO/NEOTEL-Antenna-Kit.aspx

Which i used for my Neotel modem back in the day, and it uses the neotel connectors...

My question is, Is there a connector/Coupler that can fit this antenna on a CellC Dongle?

Don't want to buy a new antenna if i can just change the connectors.

That antenna looks like it may be suitable for Cell-C (but only Cell-C) HSPA+.
You should be able to get a connector or coupler, but it will depend on which modem you have. Speak to Poynting.
 
Booster

Whilst the expert is on the line

Is there a recommended antenna / booster for mobile ( dongle // 3G router etc )
ie
Something that can improve a poor signal in a bad reception area.
