General Safety Precautions 

Do not undertake work outdoors at height unless you are  

competent in the use of ladders and other access equipment.  

Always use correct equipment, observe appropriate safety  

precautions and follow manufacturers instructions. If in doubt  

consult a professional installer.

Before starting installation check structure is sound and check for  

hidden wiring or plumbing. 

When working on an installation outside, beware of overhead power lines. 

Observe safe working practices, tread carefully on roofs and ensure 

adequate lighting is available if working in loft or roof space. 

Before making any connections switch electricity off at the mains. 

To avoid injury always route cables or wiring carefully. Ensure cable 

is correctly routed before fixing into position, taking care not to 

overtighten cable clips. 

This kit contains small parts - keep out of reach of children. 

After installation make regular maintenance checks for wear and tear. 

Congratulations on the purchase of your yagi aerial. 

The aerial is ideal for the reception of all available 

signals in strong signal strength areas. 

Assembly and Installation 

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. For vertical 

mounting rotate the aerial through 90° before sliding into the mast 

clamp.  

Loft mounting is often a viable option in strong signal strength areas 

allthough the roof may cause some loss  of signal strength. 

 

If mounting on an existing mast check that the mast is in good 

condition and firmly fixed.

1a. To assemble your aerial first slide the reflectors (4) into the reflector  

 

bracket until they click into place (make sure that the reflectors  

 

are the corrct way round as shown in Fig. 1a) 

 

1b. Slide the mast clamp onto the aerial boom (as shown in Fig. 1b).

1c. Attach the assembled aerial and mast clamp onto the mast and 

 

tighten the wing nuts until the assembly is securely attached to  

 

the mast (as shown in Fig. 1c).
