Tetrapole

Make sure the tetrapole locks into place. Do not attach the downlead yet!

Note: VHF elements have been removed from this illustration to show the tetrapoles more clearly.

Step 4: Attach the mast clamp insert

U-bolt

Mast clamp

Mast clamp insert

Find the U-bolt and mast clamp insert (see the illustration to the left). Put the U-bolt into the mast clamp insert with the teeth of the mast clamp insert facing the closed end of the U-bolt.

Insert the U-bolt into the mast clamp on the antenna and loosely thread the 1/4” hex nuts onto the U-bolt. The teeth on the mast clamp and the teeth on the insert should be facing the same direction.

Do not tighten the hex nuts yet.

Step 5: Install the transformer and coaxial downlead

Attach the transformer to the coaxial downlead (not included).

Find the 10/32” hex nuts and washers in your hardware bag.

Use them to attach the transformer to the bottom of the antenna at the studs on tetrapole.
