This Thread talks about mobile phone coverage in the Nullarbor.

The Telstra coverage diagrams that the post has links too includes coverage with external aerials.

I have a Samsung Galaxy S4 and have reviewed the manual and cannot see anything about connecting an external aerial - certainly there is no socket. So first question is can you connect an external aerial to my Samsung?

Also older mobile phones had an external aerial socket but do modern Iphone 6s and Samsungs and other similar modern models have an external aerial function.

Thanks

Garry

I "think" the answer is no through the device directly but you can get an external aerial boost by putting the phone in a carkit cradle that is hard wired into the vehicle and has an external aerial outside the vehicle. Someone might correct that if I'm wrong.

Michelle is correct. CarComm make a cradle to take the S4. I bought mine at a mobile phone outlet in Darwin several years ago.. Google should help you find one

garrycol - You can purchase a "patch lead" for the S4, which is a cable that fits to two small gold RF connectors that are located under the S4 battery cover.

The other end of the patch lead has a standard FME antenna connector that connects to any external aerial.

The site below is informative, and they sell the patch lead for $20.46.

S4 patch lead for external antenna

Cheers, Ron.

As Ron N said, there are 3G and 4G connection points behind the back cover on the S4. That company also sells new pre-drilled back covers so your patch lead can plug in without removing the cover all the time.

A bit pricey but more convenient.

Thanks for all the responses - so it looks like the connector is inside the phone - so the covers have to be removed if you want to use an antenna. Not sure the phone would like outback red dust but at least the CarComm cradle will seal the back.
To use the S4 antenna adaptor I assume there is a different back that is supposed to work with it but I do not see one listed on the website.
Thanks for the input - so it is feasible if not all that practical - just not keen on having to pull the phone apart - i was hoping there may have been a simple plug in option.
I will look for a back that has provision to plug in the aerial. EDIT - just spotted Tony's post - thanks
Cheers

You need to careful as the sockets are quite fragile and easily damaged, they are intended for servicing and not consumer use.

Thanks - like the other docks they require the rear case of the phone to be removed for use - ok if the phone stays in the car all the time but not so much if you need to take the phone in and out.

Cheers

I had a Carcomm inductive cradle (for a windows phone ) and now use it as a cradle and charger......the reception was NO better with the external aerial fitted.

Even took the aerial off and tried it up a tree to get some height.

A friend has an aerial on his bulbar. Not sure of the db and I don't recall whether or not the cradle has an inductive coil or plugs into the phone, but he has up to two bars when we have none. It certainly does give better performance when on the fringe area or even outside the coverage map if the terrain is flat.
It is handy having him in company when travelling remote. We have used his phone many times when ours didn't have signal. Both phones on Telstra, ours an S4, not sure his brand.

What Gronk Said.

Those inductive antennas are useless. I gave a few a go several years back, even on 3 phones.

A complete waste of time and money.

I later gave up on an external antenna completely. I found that driving for another 3 minutes closer to a tower has the same effect.

Even with one carrier you never know what the right frequency is.
Telstra has 850Mhz, 700 Mhz, 2100 Mhz, 2300Mhz and 900Mhz. No antenna can work with all of those.

Best thing for best reception is to get a modern bluetick 4GX capable phone

SmoothTalker have a "passive Connection" cradle for Samsung and iPhone.
I have not used one only had a look at one at Lake Macquarie Communications.
Have a look at there web site under - mobile phone solutions - phone cradles.

Hi Garry,
We use a Iphone 6s in a Smoothtalker cradle with a 6.5db aerial on a Telstra network. This will give us 2 extra bars compared with a unconnected Iphone 6s. Not sure how this will translate to real world coverage on the Nullabor. The continued roll out of the Telstra 4GX network should improve coverage for all of us with compatible phones, time will tell.

Cheers
Bryan

Have a read here

S4 advice


As said the connector in the phone is not designed for constant use and from reading about it if you damage it Samsung wont want to know you.

As said drilled backs are now available so must work I guess.

Thanks to everyone who responded certainly provided the information I was after.

I think I will look at the adaptor link and a suitable rear cover. I think that this will provide the appropriate support for the gold connector so it will not get damaged.

I guess when travelling out west I will need to use the 3g socket as 4g still has not made it to many areas - I dont tend to use data when driving so 3g will be fast enough. I assume the 3g socket will still pick up 2g though not as important as Telstra's 2g network will close in Dec this year.

Cheers

Garry

Yes the phone does that - but the Samsung has separate 3g aerial and 4g aerial ports so if the external anntena is attached to - say the 3g port how is 4g reception and vice versa.

I may be a bit late with this but try JCar electronics. They sell an external aerial that the patch lead self adhears to the back of any mobile and works by Bluetooth. All up cost of less than $100.
