Mobile Phone Antenna

Hi all,

After doing a bit of homework on here and reading reviews, I decided, and managed to find a Samsung A412 for better reception in 'fringe areas'.

I also found a genuine Samsung in car, bluetooth hands free and phone cradle for this model phone, so I'm a happy camper.

Next piece to complete the jigsaw puzzle is an external antenna, but all I can find (so far) is either a magnetic base antenna, or a 'through glass' windscreen mounted one. I'm not too keen on the magnetic base ones, (just me I guess), but has anyone got any feedback on the 'through glass' ones? Do they lose any gain being through the glass?

Also, can anyone advise if the db gain on phone antennas is like uhf radio antennas; ie, different db gain for different terrain, or is it a case of bigger (gain) the better?

Thanks in advance for any help.

Cheers, Dave

There are heap around.

Have you tried google?

http://www.google.com.au/search?hl=en&source=hp&q=mobile+phone+car+antenna&aq=f&aqi=g1&aql=&oq=&gs_rfai=

Please forget the thing about dB gain for different terrain...or you will need 50 different antennas.

Dave Hi,
The old car phones (analogue) mostly used through glass antennas without any problems a couple of times I had to replace the double sided tape. But no reception problems.

Through the glass antennas are not very efficient.
An induction type coupler, although not as good as a direct connected antenna are still much better than a through the glass solution.

Personally, I haven't bothered with an external antenna on my current rig.

The problem is, each time you update your phone, you find the old "in car hands free kit" requires replacement. I now just use bluetooth connection to the OEM handsfree solution that came with the vehicle.

The NextG phone is acceptable with reception around the major routes and towns without an external antenna.
Apart from that, we don't get stressed if we are "out of contact" for a few hours, or a few days.

Hi Bill

That last paragraph... too right. We were looking at a bush property to buy as a 'retreat' a while ago, then 1/2 way up a challenging hill on a potentially good property, my phone started ringing. Killed the sale.

Cheers, Dave

Seems it would be simpler to just turn the phone off if you like the property.

Hi Graham

Also had no running creek through it, another 'must have'. Between the two, (no creek and my mobile ringing, it was less than ideal. At the time I was in business for myself, and left my phone on out of habit. Yes, I could turn it off, but I prefer a reason rather than an excuse. No reception means just that.... not 'I am ignoring you'.

Cheers, Dave

the type of aerial you want is the broomstick type. there about 1 meter tall and about an inch thick, you put them on the bullbar. the lead is attached to the aerial and all you need is a patch lead to connect the phone to the aerail lead. You can get the patch lead off ebay for about $20. Theres one on ebay for $50. type in this number on ebay 350258645146. Thats the item number.

There is a new Omnidirectional antenna out there, built by LD Antennas in Tassie, http://www.ldantennas.com.au/omni3g_800_3000.htm

It looks weird but pulls on an extra bar or two of nextG signal over a broomstick, Also if your in trouble & really need a signal the direct wired antenna is the go. Through the glass or close coupled patch lead is Ok for rural areas but you really need direct coupled patch lead to pull in the weak fringe signals.

That said I use a broomstick on the car but if I really need a signal or want to use the phone as a modem in the Van I mount the LD Antenna ontop of a collapsible swimming pool pole, It gives an extra 50 - 200 klm range (depending on terrain) . Check "the rig" link on my website for pics www.goingbush.com

Telstra sell an RFI brand aerial which goes on the bull bar.

It is a multi band aerial and works on all the different frequencies used in Aussie.

Will increase reception by at least two bars and we found it good using both a Nokia 6120 and an Iphone.

Both have inductive connection to the carkit.

Mine cost $125 but have seen it dearer in some Telstra shops

Model no CD2195 Db gain 6.5

Thare is a range or antennas that are the Quick Fit type which are very good. We have a patch lead for 2 phone's and wireless internet.

Model No CDQ 2195. The idea of the QF is so they can be removed for low carparks etc.
