Overview
Universal Towers Packaged Tower Kits
Universal Towers Packaged Tower Kits are engineered antenna support systems using predetermined straight and tapered 10 ft. sections for a self-supporting tower with a safe maximum antenna wind load rating at a specified height. Tapered towers minimize space and weight while maintaining high strength and high wind load ratings in a completely free standing structure that is durable and reliable. Universal Towers feature rugged, heavy-wall aluminum tubing legs and welded S-bracing made of high-quality aluminum for excellent strength as well as light weight. Each welded truss section is fully assembled, finished and supplied with the required hardware for easy installation. These free standing towers can raise large antennas into the open air easily with a concrete anchored hinged base. Universal Towers Packaged Tower Kits provide self-supporting radio antenna towers that actually fit and work where guyed towers cannot.
Universal Tower packages are selected by wind load rating to a desired height. Very simply specified, the first number of the model number is the wind load rating* and the second number is the tower height. There will be no doubt that your unique combination of antennas and mast (plus rotator), with a known combined wind load, will stay safely in the air where they belong. Choose your engineered tower package from wind load ratings ranging from 3 to 35 sq. ft. covering heights ranging from 30 to 100 ft., with nearly 50 models to suit almost any location or antenna support requirement.
Choose a Standard Duty or Heavy Duty Universal Tower Package to ensure the best reliability for your antenna system. Each Standard Duty package requires a Tower Base, B-14, B-18, B-22 or B-26 to match the bottom section leg spacing in inches. All Heavy Duty tower packages model number start with "HD" and use a B-30 Base for Universal's largest 30 inch bottom section. All bases have three high capacity 6 inch hinge sleeves securely bolted onto three 48 in. steel stubs with which to anchor the tower into the customer supplied reinforced concrete tower foundation; size depends on tower model. Add the appropriate Base to your package to determine tower cost. Please note, additional truck freight costs quoted by Universal are reported by DX Engineering sales.
Universal Towers are special ordered by calling DX Engineering to determine options. Packages typically include a mast collar for a 2 in. OD mast with a welded bearing mount top plate specially drilled for the DX Engineering Advanced Design TB-300 thrust bearing, sold separately. Packages with other mast collar sizes and without bearing top plate are available by request. A variety of optional Rotator Plates are also available. Chose yours to fit the top section of the tower package selected; R-11, R-14 or R-18. Each is available undrilled or predrilled for popular rotator models, "-H" for Hy-Gain/CDE or "-Y" for Yaesu. Universal Towers Aluminum Masts in various lengths and sizes are available as well.

*Wind load ratings are to 80 MPH which serves the majority of the USA and antenna models. Specific open plains and coastal areas with occasional peak winds of 100 MPH or 110 MPH are locations where these tower packages are rated for lower antenna wind loads. See these ratings on the individual drawings of each of the Universal Towers Package Tower Kit models, linked in the "Documentation" section.
