Description: This Yagi antenna is optimised for reception of 900 MHz Cellular signals. It is our highest gain antenna available for cellular voice reception.
When your are far away from the Cellphone towers you will normally only receive 900 MHz signals. If you have weak sigal reception in Cities or Towns rather use the 900/1800 MHz all band LPDA antenna (see left)
This Yagi antenna covers the 900 MHz voice bands. It has a gain of 14 dBi and is very succesfully used to improve reception in rural areas.
In the box you will find:
- High gain Yagi antenna
-
2 x U-Bolt, 2 x Econo bracket, 4 x Washers and 4 x Nuts
-
10 meter cable
-
Universal adapter that fits onto any cellphone
This antenna covers the 900 MHz band only and should be used in remote/rural areas only. The cellular towers in the rural areas uses 900 MHz only. As soon as you are using your phone in the urban areas you need a dual band antenna like the LPDA-A0021.
Installation: The antenna is supplied with a U-Bolts to fit on a pole up to 50 mm in diameter. Please note that the wall bracket and mounting pole is not included. Please have a look at the left for wall brackets and poles.
Mount the antenna on a pole outside the home or office. The antenna must be installed as high as the cable allows. It should be pointed in the direction of the cellular tower. Have a look here to get more advice on installing the antenna. Take the cable into the house or office and connect the 10 m to the 30 cm long phone adapter cable. The other end of the adapter cable gets held against your phone.

Commonly asked Questions: (Please see more FAQ here)
The word is the name of one of the Japanese inventors of these directional antennas. The other inventor's name was Uda so in technical circles these are Uda-Yagi antennas in honor of the inventor team. The invention is from the early 1900s.
While there is a multitude of directional antenna designs in use today, the Yagi is the most popular, well known and most seen.
What is the difference between a YAGI and a LPDA?
A yagi antenna typically can only cover 1 of the 3 cellphone bands (900MHz/1800MHz or 3G, 1950-2170MHz). GPRS is transmitted on 900/1800 bands, 3G/HSDPA on the UMTS 2000MHz band. Very likely that yagi is not made for the 3G band in which case it may actually REDUCE the signal at 3G and enhance GPRS. Best to use a broadband antenna such as an LPDA (log-periodic dipole array). These antennas do all the bands and may solve the problem.
If the elements (vertical sticks on the picture above) is the same length, it is a YAGI. If the elements gets shorter to the one side it is probably an LPDA.
I would like to have a repeater or system that transmits, that I do not have to be connected to a cable when talking on my cellphone?
Unfortunately it is illegal to transmit on the cellular frequencies, the Cellular Network Providers are the only ones that can transmit on these frequencies. Therefor we cannot sell systems that radiates the signal. Our solution requires that you connect the cellphone to an external antenna with a 10m cable that and an Universal Adapter. Only one cellphone can be linked to the antenna at a time.

Unfortunately it is illegal for anyone but the Cellular Network Providers to transmit on the cellular frequencies; or that radiate the signal. MTN and Vodacom have a license with ICASA to transmit on the frequency range. That is exactly what these ‘extenders’ do. Therefore to buy these systems over the internet (from other countries) and installing it here in South Africa (by you) is illegal.
The problems with these repeaters are that they are expensive and, if they are not installed properly, they will influence the network negatively. If MTN, Vodacom, Cell C or ICASA ‘find’ these repeaters they will remove it and you might be liaible for a fine.
There is a coupling loss between the coupler and the cellphone antenna and this varies between -3dB and -6dBi (possibly even more) depending on the efficiency of the cellphone antenna. This is why we use a high gain antenna and low loss cable to overcome this loss.
