The Cel-Fi GO requires both a minimum of two antennas to operate; one internal and an external antenna. A Cel-Fi GO can operate with multiple internal (donor) antennas however this is usually considered a bespoke solution and is best to get in contact with a qualified installer or Powertec consultant to verify.
A Cel-Fi PRO solution does not always require an antenna. If you have sufficient signal (at least 2 bars) then it is likely that the existing internal antennas will be sufficient for your needs. If you have very poor signal then it is highly likely that you will need an external antenna.
Powertec has access to Australia-wide cellular frequency information and offers free consultation to all of our customers should you feel unsure about which antenna would best suit your situation. Email us at [email protected] or call our head office on (07) 55 770 500 to discuss today!
Internal Antenna Options
Internal or ‘donor’ antennas go inside the building and distribute the signal amplified by the Cel-Fi GO repeater. The majority of our internal antennas are wideband meaning they encompass all currently available bands in Australia (3G, 4G & 4GX).
Wall Mount Panel Antenna
698-4000MHz (5/ 7dbi)
Able to be wall mounted, this antenna is directional – meaning it’s signal is dispersed primarily within a 90° beamwidth in the direction the panel faces. It’s ease of installation and non-obtrusive appearance makes it ideal for pushing through long spaces or lightly walled areas (ie. home environment, sheds, dongas)
Ceiling Dome Antenna
698-4000MHz (1.5/ 4dBi)
This ceiling dome antenna pushes signal out in a 360° beamwidth making it ideal for offices and home environments where ceiling mounting is desirable.
Adhesive Mount Antenna
This antenna is easily hidden measuring ~10cm long with an adhesive back. Used primarily for marine, caravan and car applications where other internal antennas are too strong to achieve the required isolation. If you do not have enough distance or a suitable barrier between the external and internal antennas, the system will not work.
External Antenna Options
Directional – These are high gain antennas which need to be aligned with the signal source. They are able to pull signal over large distances (60km+) where clear LoS (Line of Sight) is able to be obtained. Best used in remote locations or where signal source location is known.
698-890MHz (14 dBi)
One of the highest gain antennas on the market. Able to ‘grab’ signal from long distances but also requires precision alignment due to its narrow beamwidth (5-10°). It should also be noted that this antenna is not wideband meaning that it is able to receive 3G & 4GX frequencies but not standard 4G frequencies (1800 – 2100MHz).
This is the general ‘go to’ antenna – wideband (covering 3G, 4G & 4GX), providing good gain with a forgiving beamwidth (15-20°) the Blackhawk LPDA suits most rural, regional and urban situations. It does need to be aligned with a source signal, however does not require the same precision as the Yagi. Choose if you want powerful gain for any of the major networks in Australia.
698-2700MHz (8/ 9dBi)
This ultra light LPDA antenna needs to be pointed towards the direction of where the signal is coming from and pole mounted. Similar to the previous LPDA model however with less gain (less range) and a more ascetic appearance. Perfect for urban or suburban environments.
Omni High Gain
An omni-directional antenna does not need to pointed towards the direction of where signal is coming from and will receive a signal from 360 degrees. It can be roof, gutter or wall mounted. Not recommended in low signal areas unless LoS cannot be determined.
