Having moved to regional Queensland to discover poor internet
(meaning no Cable or ADSL at the time), I tried Satellite with
Reachnet and Telstra as a first attempt. but the speeds were
Townspeople had reasonable Wireless Internet speeds but being 25km from the transmission tower meant having to overcome the challenge of distance.
As an amateur radio operator I understand propagation and could see the possibilities of an external antenna and could build what I needed.
If you zero in on the Wireless frequencies that you wish to capture,
you can build the right antenna.
My focus was Telstra/Bigpond Next G only... If this isn't your desired band, then you need to adapt for your location and Telco.
Using a borrowed broadband modem, with an external antenna port, and using a generic VHF antenna I improved the receive signal. This gave me heart to continue on and build a better Yagi beam antenna resonant on 850MHz.
8 Element Yagi - a uni-directional antenna. Black plumbing pipe & 10mm dia. aluminium tube elements
Drill holes at precise measurements, insert elements, leaving space for the Driven Element
The D.E. is basically a Dipole, equal lengths cut to resonant frequency.
White PVC was ideal diameter to fit over black poly beam and to
hold the D.E.
Inserted the coax feedline & terminated ends of coax with ring terminals. Note very small holes in aluminium driven element. The ring terminals were screwed into the DE holes inside white pvc fitting.

" Telstra will be switching off 3G in 2024. Before switch off, you can use handsets supporting 3G on 850MHz... After switch off you will still be able to access the Telstra Network on 700MHz." Find out more at: Telstra 3G is Closing"
I found some some good modeling information at
VK7JJ Next G Yagi
and Phil's work assisted my Yagi project.
By the way, I know there are commercial antennas which cost at least $200 but I found they were "one-size-fits-all"and not exact enough for my frequency, besides, making your own is so much fun.
This DIY Yagi costs less than $20 so if you'd like to make one, now you know how. ENJOY
