Ideal for Wireless-N (802.11n) Technology
The TwinPol Antennatm has been specially built to Freenet Antennas specifications. We all know that 802.11n is the fastest WiFi technolgy to date - but to get that speed you need multiple antennas. And to get a decent distance (our speciality), you need directional antennas. So we asked our primary antenna manufacturer to build a special antenna that was a special two-in-one antenna with a combination Horizontal/Vertical polarisation antenna in one enclosure.
The advantages of having two antennas in one are:
- Easier to Point. With directional antennas, you need to point the antennas in the desired direction. Pointing two antennas on one mast is not easy.
- Easier to Install - compared to two separate antennas.
- Better looking - compared to two separate antennas.
Features
- Twin Polarisation - Vertical and Horizontal. Ideal for MIMO (Multiple In, Multiple Out) applications such as 802.11n.
- Two N-type female connectors. This allows you to connect two 802.11g APs or one 802.11n AP.
- High gain, low profile
- Outdoor use. Corrosion resistant
- Supplied with mast mounting kit. This kit includes adjustment for elevation (up and down)
Performance
At Freenet Antennas we like to do real-world tests rather than relying on just specification sheets. See below the results of some real-world TwinPol Antennatm tests.
TEST 1
- Distance: 0.91 km
- Speed: 80 Mbps
TEST 2
- Distance: 1.84 km
- Speed: 60 Mbps
Mounting
Comes with a free pole-mount kit, as shown in this picture. The pole mount kit allows both elevation and azimuth adjustments.
