Correct assembling sequence for all the bolts: bolt, serrated washer, normal nut, two flat washers
and self-locking nut.
Lock all tightening bolts thoroughly normal nut. On this bolts will take place wire
radial ends.
Continue the assembly with the two insulators in which is placed the wider and lower pipe section
40mm. Leave loose bolts so you can easily move the tube into its final position with the lower side
protruding approximately 2cm from the insulator. Install on the tube end a 4x20MA bolt and lock it,
insert a flat washer, eyelet RF wire, another flat washer and normal nut. Lock bolts of isolators and
assembling the RF choke coil (choke). Making sure that the coil is vertical for a better rain
drainage. The choke will short to ground any electrostatic discharge and will reduce noise.
The care and precision of this assembly will ensure a long life to the antenna.
Check that all bolts have been properly secured and completed the radiator assembly.
With the aid of the U bolts, install the base on the supporting pole and install the wire radials.
The U bolts are 50mm wide, it can get poles or tubes from 40 to 50mm.
As radials being installed, take care doing the work as they can also heavily influence the final
tuning. You may have to try to attempt the best point of risonance.
