This will complete the assembly of your DSEFO144-6RS. The construction of this 

antenna will provide many years of consistent performance with no degradation of 
performance due to corrosion and weathering. 
 
 

You are now ready to install your antenna. Install the 3 x 5” boom to mast plate 

between D2 and D3 at the balance point. The small U-bolts fasten the boom to the plate. The 
larger U-bolts attach to your support mast.
