Professional High Gain 48 Element
Group A Aerial
LABHG48A USER GUIDE
Congratulations on the purchase of your LABHG48A 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:
• 14.0dBi Gain
• F type connector for secure and easy connection
• Fast simple assembly
• Encapsulated weather resistant electronic balun

Installation Instructions

For optimum results install the aerial using double screened CAI benchmarked digital coax cable
(for the downlead) and screened coax outlets (not supplied). Use the F connector and weather boot
supplied to connect the coax downlead (not supplied) to the F socket on the aerial.
1. Prepare the Coax Cable: Firstly 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 as 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.

sprung studs to hold it in position as shown in Fig. 4.
5. Using the reflector clamps, bolt and wing nut, fix the reflector
assemblies to the main aerial boom as shown in Fig. 4 and Fig. 5.
6. Check that the reflector clamp tabs locate in the
holes of the reflector boom sections and that the
wing nut is tight - see Fig. 5.
