external antenna help

Post by odes » Tue Jul 07, 2009 1:49 pm

i've been able to get reasonable reception by using a laptop outside and finding
the position where the best reception is gained.
> Speed has been ok, and usually get 3-5 bars.
> We want to use the HSPA connection in the home, obviously the paddock isnt the best office, however there is very low
reception in the house, not enough to make a good connection.
does anyone know the best type of external antenna and cabling for the Huawei E169 to go out on a pole in the backyard so that we can get
reception in the house? i would probably need a good 15-20 metres of cable.

This topic popped up yesterday. You could start here and work backwards http://forum.exetel.com.au/viewtopic.php?f=308&t=32701

Your aim is to get line of sight to the transmitter and to keep the cable short to avoid losses which cancel any gain. You should try going up rather than out in the yard - it might work under the eaves, or on the roof, with a consequently shorter cable run. If you can keep the modem out of the weather, it could be at the end of a long usb cable. Professional antennas come in several forms with differing gains (look for Virgin/Optus 3g), and often quite adequate ones can be made from woks and jam tins.

PS If you find an inconvenient place where a short cable works, you could put a suitable router there and use either ethernet or a wireless LAN to serve the spot where you want the computer.

jam tins.

jam tins
Hmmm I am old enough to know what you are talking about, I guess jam still comes in tins :D
Your usual very helpful post Dazzled :D
A friend of mine has borderline signal strength, but sitting at gutter level at his verandah edge, he has 86%-90% signal, as he has power adjacent we are going to devise or purchase a weatherproof housing to house a router and do the longer spans with patch cable to a AP indoors.

Munka, these are just for you in the bush (though you seem to have moved)!

Yep moved to the big smoke, pop.3600 :D

Though plenty of wide open bush around here, excellent links, I have been aware of cantenna's for some time though never got around to making one and the RFshop has all the bits except the jam tins :D

Edit: RFshop have good prices on enclosures too. http://www.rfshop.com.au/Products/Hardw ... fault.aspx

Munka, I should also have posted this antenna/router solution, if you haven't found it already - http://www.rfshop.com.au/ContactUs/Blog ... fault.aspx (but use a 3g router)

I read a post on a whirlpool forum that Exetel were going to import and sell
900Mhz Yagi's. Does anyone know if this is correct..??

Thanks, yes found that, looking closely at this one, second to bottom of page $111 looks good.

Hi Log Cabin, I believe the elusive yagi's were still on order last I heard, just needing a solution now.
Perhaps someone that actually knows could comment.

thx for the help guys. i got on the roof with the laptop and the modem on a 5m usb cable on a long stick to get as high as possible, but still unable to get reception. im in a blackspot, except for that one spot where i get good reception in a spot about 6ft square

From a post 4 months ago Exetel's "NBN" Get's A Little Closer....... ..
Over the past few months several of Exetel's country agents have been installing HSPA services on rural properties using Yagi antennae to address the distance from base station issues (up to 30 kilometers in several cases) with considerable success. The current drawbacks are the cost of the antennae and the lack of a full functionality 'magic box' that has a sim slot (rather than a USB port) and a built in ATA with two lines to take the customers current telephone hand set.

Exetel has been trying to source a suitable Yagi from the PRC over the past two months to reduce the antenna price from something over $A130.00 to something under $A50.00 (including the patch leads) and also sourcing the 'magic' box for something like $A150.00 to give a one off install hardware cost of sub $200.00 plus whatever an agent wanted to add as a hardware margin plus whatever the agent wanted to add for installation. In this way the end user gets a much lower cost installation than they would be able to get from any other carrier/agent but the agent will be able to make more money because Exetel has 'procured' much lower cost hardware.
From a post about 6 weeks ago Time For A Sea Change.......
While I'm happy enough that we will get a sensible level of 'pricing support' from Exetel the key issues of antennae, 'USB modems' and magic boxes will need to be addressed by us. I believe we will have a good antenna solution (subject to last minute hiccups) and we appear to be close to getting a much better price for the USB 'sticks' but the magic box is still elusive. Perhaps we'll get some inspiration from the last of the marketing experts we have briefed on our desire to promote HSPA?
There is a reply in that thread that raises possibly the most important issue/s with getting the right antenna for the specific location ..
I just had a local radio buff here in town rig up a 900 Mhz yagi for me (from an old UHF antenna).

Tested in an area about 15km from the tower, slightly obstructed by a hill/trees, that had no signal at all.

Connected the aerial, had a full 5 bars on the meter, at chest height, without mounting on a pole.

Just shows that having an antenna can make all the difference.
.. and that is, having a competent person on site, to lend a hand in setting up the right antenna. There are many areas of rural/remote Australia where Exetel don't have agents, and it is in these areas, that HSPA is ideal, given that reception is good, which all depends on getting the right antenna/cabling, which usually depends on competent on-site support (Exetel agents ?? )

Of course Optus coverage must be there in the first place, although the coverage maps are not entirely accurate.

Odes, you might need one of these - http://www.poyntingdirect.co.za/Product ... HSPA-A0001
(Same idea as the RF shop solutions mentioned above)
