18 Element High Gain Group A Yagi Aerial
LABGT18A USER GUIDE
Congratulations on the purchase of your LABGT18A aerial. The aerial is designed to get the best reception
from group A transmitters and receives signals between 470 and 606MHz. The high gain performance makes
it ideal for reception in fringe areas.
Features include:
• 15.0dBi Gain
• F type connector for secure and easy connection
• Fast simple assembly
• Compact pack for easy transportation
Installation Instructions
For optimum results install the aerial using double screened CAI benchmarked digital coax cable
and screened coax outlets. You will need to fit the coax cable with the F type connector
supplied to connect to the downlead (not supplied) to the F socket on the aerial.
1. Prepare the Coax Cable: First fit the rubber weather boot provided, to the aerial end of
the cable. Strip the end of the cable as shown in Fig. 1. Once you have stripped the
cable, twist the braid and pull it back on itself, make sure that no braid is touching
the copper core, this will cause a short on the cable and you will not get any signal.
2. Fitting the F connector: Now, simply twist on the 'F' connector supplied and trim
the central conductor.
For best results the aerial should be mounted on an outdoor aerial mast and pointed
in the direction of the nearest transmitter* making sure it is in a position where the
transmitter signal will not be obstructed by nearby trees and buildings. If you are in
any doubt about the direction in which the aerial should be pointing or the
orientation of the aerial (horizontal for main transmitter, vertical for relay transmitter)
check your neighbours' aerials.
The aerial requires some assembly.
If mounting on an existing mast check that the mast is in good condition and firmly fixed.
