Blast from the past ( please move if currently in an inappropriate subforum )
When we moved to Wamuran QLD ( D'Aquilar Hwy ), we didn't have ISDN anymore and had to resort to analog ADSL, getting less than 2Mbps on a good day ( regional tariff ).
I applied for and became a Node to BRISMESH, this must have been around 1999-2000.
Used a pre-loved D-Link DWL900AP in 2001 ( brought it back from the UK then ) and prior to that used a Senao adapter. Both were linked to a preloved lappy ( Packard Bell, broken display connected to an external monitor ).

At that time, the nearest major node was around Tenison Woods Mountain ( ca. 570m ) at about 60kms away LOS. A mate had just moved to Mount Mee, being closer, took some equipment to his new lodge, mainly Seanos & D-Links.
This was about 10km LOS.
I ordered the Mother Devil Antenna from Ken of LD Antennas, Tassie for less than $100 delivered with a generous RPSMA pigtail:
After about 36 hours of trying we had a stable signal of 11Mbps - not bad !

Re: Long distance 2.4GHz WiFi
Interesting idea, could I use something like this or similar to share wifi around my 10 acre property?

Re: Long distance 2.4GHz WiFi
When some power emission laws have changed since, but yo can do it for a much shorter range without a 2.4GHz amplifier.
The EIRP ( Effective Isotropic Radiated Power ) regulations are on the ACMA website.
https://www.acma.gov.au/australian-radi ... ctrum-plan[/url]
Between the ranges of 2400 MHz to 2483.5 MHz, the limit is a maximum of 4 W (watts) EIRP.
For 802.11/802.11b applications, this means Channels 1 through 13 have a maximum limit of 4 watts EIRP
EIRP calculation
EIRP = Tx power x Antenna Gain / Feedline Loss
OR
EIRP = Tx (dBm) + Antenna Gain (dB) - Feedline Loss (dB)
e.g. 30 mW WLAN card into a 24 dBi dish with 3dB coax and connector loss
30 mW = 15 dBm (from PowerAndGainToDecibels)
EIRP = 15 + 24 - 3 = 36 dBm
This system is right on the legal limit of +36dBm (4W) EIRP.
