External phone aerial

Has anyone used the aerial boosters that stick to the phone. I saw them on ebay. Do they work? If so, it might be cheaper to just stick one of those to the 3 phone.

Someone gave me one of these things, so I stuck it on.........

Does nothing

The "new 3G" is actually a form of CDMA (not compatible with the current CDMA) and because it operates in the same band and is a similar system, should have much the same coverage, except it will have all the 3G bells and whistles including wide band.

Hi JDNSW,

The info I came across regarding WCDMA ie 3G etc is that it has effectively the same range as GSM, and it does'nt equate to the old CDMA range.

3 Com and Telstra have done a meal deal sharing their respective GSM and WCDMA network infrastructure, whilst Vodafone and Optus are teaming up to do likewise. Hence, why most 3 Coms are bouncing of Telstra GSM networks in regional areas. Telstra's market into WCDMA are bouncing of 3 Com.

Some phones, capable of offering both WCDMA and GSM capabilities does not help the traveller seeking the older CDMA distance coverage.

Bugga, they are turning us in for market share in the addon benefits of broadband services via mobile in lieu of a decent phone coverage across our vast continent.

Part of the problem is that the term "3G" is used so loosely that it is useless. There are currently a number of services described as 3G and actually using WCDMA technology that do not operate in the same frequency band as Telstra's proposed new service. Currently there are no commercially available phones that operate in the new band, and there are only a few test installations operating intermittently, so it is impossible for anyone outside Telstra to know how well it works. For their part, as recently as last week Telstra have discounted claims that coverage will be less than CDMA and have said that they are still guaranteeing the same or greater coverage.

My concern is how much it will cost!

I live at Mullion Creek (24km Nth of Orange) & on CDMA with no mobile service when in hand. Rangie has RFI 6.5db Bull Bar mounted aerial & phone in cradle I get two bars on my phone.

Defender has Laser 6db aerial bull bar mount and reception the same as the RFI aerial. Both aerials made in Australia.

I was thinking of chimney mounted aerial running of 12volt transformer for reception in house on CDMA, I guess it should work?

Can't see why not.

I took his advice, i'm glad i did cause i found out later he was correct, i tested ours against a mate with an external antenna, made no differance, infact his in some places had less signal:D

I find this very hard to believe. in fact it is rubbish. I have been using CDMA since the closure of the analogue system. I have a full car kit and an external antenna. The external antenna makes a huge difference to the signal strength and I have proved it many times experimenting with different antennas and without an antenna. If you are driving in the country and use CDMA then I suggets you buy a decent name brand external antenna (not on glass). I use a Mobile One version but there are others that perform as well.

I work in central queensland where cdma is the best and work have given me a GSM phone :rolleyes: , I am not sure of the strength but I have a big black external aerial attached to the bullbar and without it I may aswell chuck my phone in the bin. Out of all the vehicles in the company my aerial is the biggest and I get the best range.

Simple, the best antenna for you is the RFI CD1795 which works better than any ofthe other manufacturers products and also has a higher grade stainless steel spring that you wont see rusting. The CD1795 will also cover both the CDMA (824-890MHZ) as well as GSM (890-960MHz) in the one unit.
