Antenna assembling instructions:
Take antenna parts out the box and find the semi-dipole main alluminum tubes. They are pre-assembled
inside the other tubes in a telescopic sequence. Tilt down the main tube end and shake it to have each one
inner tubes heads out for about 15 cm or 6 inch. Make sure to have enough free space to extend the entire
semi-dipole. Pull out the smaller tube, find the passtrought hole on the inner end, make it coincident whith
the passtrought hole present on the next diameter tube which has two different diameter holes, from the
larger hole side insert and push down the hallen screw passing trought the inner tube hole, put washer and
selflock nut and screw down.
Make sure to have the bolt head as in the picture below. Do not forget to lubrificate the stainless steel bolts
or nuts before to install them. Any kind of oil or grease is ok.
Do the same way for the other tubes joints. Some inner ends have more holes, they will help you in
tuning antenna on your preferite band section, use the one in the middle for now.
Make sure to have heach one tubes connection having bolts head on the same side.
When completed, insert on the semi-dipole end the trap set (following the sequence 10m, 15m) Bolt down
each one tube joint following the same way used before. Traps sets are pre-assembled already but joints in
between traps, have multi holes on the inner tubes, improving antenna tuning steps if necessary. Longer
antenna lower frequency, shorter antenna higher frequency. Start tuning operations from the highest band
Any new tuning step on the higher frequency will have effect on the other lower bands.
Make sure to have traps drainage holes on the lower side.
DO NOT seal
the joints with adhesive tape or other similar element, the antenna MUST breathe
otherwise you may have serious problems over time due to condensation or moisture.
When the two seeds are ready, prepare the central plate and assemble all the parts as per photo. The
two dipole ends must protrude from the insulator of 2.5cm and a spacing of at least 1cm
