I was doing some digging around online with map programs to try and work out what the tower is that I have direct line of sight to from my house. I worked out that the distance is 10.3km and I managed to find it's location and get a clear pic of it using my local free high resolution areal map program.

I spotted it about 4 years ago through my telescope as it's not visible with the naked eye. Looking at online mobile phone tower maps it isn't showing up on any of them (there is a Telstra tower a few km from it in the same district and I have driven past that one though it's not the one i can see line of sight from out house. This tower I can see has areals on it and what looks to be some kind of significant infrastructure at the base.

The hill that it's on has good coverage to the valleys below

At my place I have mobile (voice, text only) coverage if my mobile is placed on the kitchen window frame in one location. Though if you pick the phone up you loose the signal. I use a bluetooth cordless phone that pairs with my mobile and all landline and mobile calls are accessed through the cordless phone handset. This avoids having to physically touch our mobile handsets and drop the call. This works fine though is a bit of a pain having to remember to pair your mobile and leave it in the one location all the time.

Would be great to find out what this tower is for and if it's going to be any use to me now or in the future. Perhaps it might be used for fixed wireless NBN and I could have a receiver aimed directly at it in the future (10.3km a issue?) Or perhaps 4g or something like that.

The biggest issue in my area is all the hippy's (who drive to the town meetings in smoke bellowing VW combi vans :lol: ) with there copper foil helmets firmly in place jumping up and down every time a tower is proposed for the NBN or mobile phone. If it wasn't for them we would have had progress years ago. They are making a already hard infrastructure project even more difficult. :evil:

What I could dig up on the tower pics.

Hi OffGridQLD,

I had a similar issue. You can see my solution here....

Kurt, get yourself the Network Signal Info Pro phone app, it tells you which tower you are conencted to, range, signal strength, plots to GE etc.
Its a bit hard to reconcile that aerial photo with your telescope photo - the big chunky bit on top with a tower on top of that in your photo doesn't quite look the same as what's in the aerial pic, although it may be outdated of course.
Try taking a photo right on sunrise before too much dust and smoke has built up, and the seeing (turbulence) should be much better then too.

APR, yes your situation sounds very similar. The aluminum window must be the key to it as sitting my mobile on the kitchen bench a loose the signal even mounting the phone to a suction mount on the window results in no signal. The phone has to be resting on the frame. Another key thing is the window cant have aluminum fly screens as they tend to act as a Faraday cage.

Image

My iPhone shows a signal of around -109 some times a tad better. My wife's $20 android phone shows one bar and shows 3g but the same minimal week signal.

That window looks straight out to the gap in the hill that you can see get line of sight to the tower 10.3km away
Image
I'm just not sure what that tower I can see is broadcasting.

At the moment we have ADSL at the house but average speeds are only 3.5mbs at times as high as 4.5 and as low as 2.5mb so hardly impressive considering your paying for adsl2. It's a stable line but just thinking if I could get 3g at 3mbs i could just kill the land line altogether.

I assume the 3g modem you used had a external areal input to it to use the antenna?

Thanks Gordon,
Yes that distance across land when people are back burning and its 32C + holding a iphone to scope to take photo doesn't = a crisp image.

I spent some time making sure the references to determine the line of sight was correct from my house and that's the only tower within sight allowing for a good margin of error in the search cone. Though the pic through the scope hasn't changed much over the years and the areal pic is 2015.

This is s low resolution google maps 2017 image

The phone apps sound like what i need to spend some time with ...I will do some research.

I got this photo just as the sun was setting. I tried a 6mm eye piece instead of the 24mm I had in before. Way harder to hold the iPhone steady for a clear shot with that magnification ...particularly with a 10yo running around on the timber floors :roll:

Image

unfortunately my wife's phone (Network Signal Info Pro ap was only available on android) doesn't have enough memory to download the app. I managed to clear some space to install the app then it wanted more space to update some service in google asking if I wanted to delete the app to make room for the service update :lol: so I could use location info and show maps within the app . The app Wasn't available on I phone.

Next time some one is at my place with a somewhat better than $20 android phone with free memory space I will get them to download it and give it a go.

G'Day Kurt,

Go to this site....

http://web.acma.gov.au/pls/radcom/assig ... nge_search

...and put you postcode in both the low and high postcode boxes, put in 650 for the low frequency and change the frequency drop down to MHz, put in 2700 for the high frequency and change the frequency drop down again to MHz, and then click on Run Enquiry. You might get some useful info on who has towers in your area.

Here is a bit of info on the tower frequencies for the various OZ providers ....

One thing I did stumble upon in my searching was new listing for 50 acres for sale in the valley below me with a fixed wireless NBN tower application.

If that gets the go ahead then that would be just over 5km away and clear line of sight.
