TiltPlate - Stacking

Stackable TiltPlate

The stackable TiltPlate configuration allows the mast to extend above the TiltPlate. The boom truss u-bolts are positioned so the boom truss mast and cables do not interfere with the main mast in the normal or tilted over position. The normal offset of the moveable plate insures there is no interference between the main mast and the boom truss cables. There is an adapter for the KARLock to use it with the stackable models. Click here for the KARLock page and a picture of the adapter.

WARNING: Stacking TiltPlates or mounting another antenna above a TiltPlate will put a significant additional load on your tower, mast, and thrust bearings. Be sure to consider this when designing your project. Array Solutions is an excellent source for information on heavy duty masts. If you are considering an extended mast, this is worth a read: http://arraysolutions.com/Products/masts.htm

The stackable option was tested in the summer of 2009 by Steve/W4QMC, Jim/KE5JCN and Bob/WA5VSK.

Stackable configuration now available at no extra cost.

Diagrams showing the "stackable" TiltPlate operation with a second "standard" TiltPlate mounted above. Note: instead of mounting a second TiltPlate on top, this is an excellent way to mount a 2M yagi and/or a vertical or ground plane above your yagi antenna. It can also be used to mount a 30M or 40M dipole above your yagi.

Note: In Bob's installation, the boom truss cable is attached to the main mast. The preferred method is to install the boom truss mast on the moveable plate of the TiltPlate. The cable tension is then kept constant as the tower is lowered.
