IMPORTANT WARNING READ BEFORE USE!
WE HAVE DESIGNED Towermate TO WITHSTAND WIND GUSTS UP TO 130kph WITH A MAXIMUM ANTENNA PROJECTED AREA OF 3.9m2. THIS DOES NOT MEAN THAT YOUR INSTALLATION IS SAFE TO CARRY SUCH HIGH LOADS.
YOU ARE SOLEY RESONSIBLE FOR THE SAFE CONNECTION AND OPERATION
OF YOUR Towermate. AS PART OF YOUR INSTALLATION YOU MUST ENSURE THAT
ALL OF YOUR INSTALLATION IS CAPABLE OF WITHSTANDING ANY LOADS ARISING
DURING OPERATION AND LUFFING.
Towermate is shipped fully assembled ready for you to mount it to your
installation and requiring only your preferred boom fixing clamps for completion.
Towermate is shipped with the two main plates zip-tied shut to avoid any risk of
finger trapping hazards when you remove it from the packaging.
Towermate has been designed to minimise the risk of finger trapping hazards
(especially around the main pivot shaft). However, it is still possible to get your
fingers into the minimum 10mm clearance between the two plates which would
of course be uncomfortable and should be avoided.
1. Leave the zip ties in place on your Towermate until after you have carefully positioned the 4 U-bolts over your lowered (horizontal) stub mast.
2. In order to tighten the 4 U-bolts you will now need to cut the zip-ties. Do this with one hand whilst at the same time supporting the bottom plate being held by the zip-ties. Carefully remove the zip-ties and lower, under control, the bottom moving plate to the vertical position. Keep hands clear of the main shaft when doing this as the boom plate will swing down quickly under gravity.
3. Now that the boom plate is hanging nearly vertical, it is possible to access the nuts and to
tighten up the 4 U-bolts to secure your Towermate your stub mast.
4. Offer-up your boom to the hanger brackets which are located at the bottom of the boom
plate. These plates are pre-machined to accept standard 4”, 3” and 2” booms. If you have a
different boom dimension you may need to drill additional holes in the hanger brackets to
allow fitment of your boom. For example, a 40mm square boom on some Optibeam antennas
can use the existing holes furthest away from the stub-mast plate, requiring that you drill
just one additional hole (7mm dia) in each bracket to suit the spacing of your square boom
For round booms please align the antenna elements so that they are parallel to the hanger
brackets, this will ensure that the antenna is set parallel to the ground when your tower is
vertical. You may need to use a suitable trestle help to raise your boom to the hanger
brackets, or you can of course enlist the help of a friend to do this.
Once your boom is fitted you should check that it is hanging level which will be a good indication that the boom is centrally positioned in the Towermate you can take measurements to confirm this.
Please take some time to make sure that all of the fasteners are correctly tightened to the specified torques. Tighten the supplied M8 U-bolts which attach the Towermate to your stub mast to torque of 23Nm. All fastners except for the boom hanger U-bolts have been correctly torqued and dabbed with loctite for safety and security. Follow the instructions which came with your antenna to identify the correct tightening torque for your own boom clamps.
Now that everything is secure, you are ready to raise your tower in the usual way.
Towermate will automatically pivot on the main bearing shaft, and once your tower is vertical the boom-plate will automatically lock into the stub- mast-plate ensuring that your antenna is correctly deployed even in the event of high wind loading.
Please ensure that sufficient clearance is available all around your installation and NEVER allow anyone to stand underneath the tower or antenna until your tower is safely locked in the vertical position.
If you need to lower your antenna for any reason, simply do so in the normal way and Towermate will automatically un-lock as the tower rotates away from vertical allowing the antenna elements to stay near-horizontal such that once the tower is fully lowered you have full ground-level access to your installation.
