TOWER KIT DESCRIPTIONS:

Full Tower Kit includes cut and drilled 6061 aluminum parts and stainless steel assembly hardware. The assembly and installation manual can be downloaded from this web site. Mounting bolts are not included.

Custom and Semi-Custom Tower Kits If you have a roof top tower requirement that isn't shown, please drop me a note and I will see if I can make it. I can upgrade the ability of the non-HD towers to handle heavier antennas by increasing the rotor bracket and shelf wall thickness.

DIY Tower Plans include instructions for cutting and drilling all aluminum parts. The full instructions are downloaded from this web site, and the password to unlock the instructions is emailed to you on request. The assembly and installation manual can be downloaded from this web site. Assembly and mounting hardware are not included.

THRUST BEARINGS:

My towers are designed to work with a thrust bearing mounted on the top. I recommend the Yaesu GS-065, which will handle up to a 2.5 inch diameter mast. You could also use the Yaesu GS-050 thrust bearing, however this will only allow masts up to 2.0 inches OD. You can save money on shipping by purchasing your thrust bearing locally, either new or used. If you plan to use the GS-050, please tell me so I can drill the mounting holes for this bearing. If you want all tower parts to arrive at the same time, I can purchase the bearing and include it with the tower shipment (use the -065 or -050 option).

Warranty

W8IO Rooftowers LLC warrants all its roof-tower products for 90 days after shipment. If any W8IO Rooftower fails to give the purchaser complete satisfaction within 90 days of shipment, we will replace any component of the Rooftower free of charge. W8IO Rooftowers LLC will not be liable for loss or damage to property or incidental or consequential loss or expense from property damage due directly or indirectly from the use of this product.
