ROHN 25G Tower Sections & Concrete Embed Bases
Since there are various other Manufacturers of Towers and Tower accessories that copy the ROHN Tower design, if you are not sure of the manufacturer of your Tower, you can at least compare the actual measurements and design of yours to those found in the spec. sheets of the ROHN catalog section via the Link provided above to assure yourself that additional sections or parts will fit. We cannot make that determination for you as the ROHN clones are something we don't carry or otherwise represent in our Product line. We can pass along to you that ROHN GT Series Towers have a Zig-Zag Lattice that starts from the right at the top, whereas most clones start from the left!
All towers in the GT Series are constructed with high strength steel tubing and feature ROHN's exclusive Zig-Zag ® solid rod bracing to provide exceptional strength and are hot dip galvanized after fabrication. In this process, each section of the tower is totally immersed in molten zinc, allowing every square inch of the tower, inside and out, to be completely covered. Hot dip galvanizing protects all points of welding and construction against rust and corrosion while providing an attractive finish.
There is a lot of conflicting information out there about the difference between the ROHN 20G and ROHN 25G. The following is factual information based on the invocation and use of the word ROHN, as to delineate the distinction between ROHN and any other Manufacturer or Clone. The ROHN 25G 10 Foot main Tower Section weighs approx. 37 lbs., whereas the ROHN 20G 10 Foot main Tower Section weighs 30 lbs. The ROHN 25G Tower Section is 16 gauge steel Tubing, whereas the ROHN 20G Tower Section is 18 gauge steel Tubing. The ROHN 20G 10 Foot main Tower Section consists of 6 bays spaced approximately 18.25 inches while the ROHN 25G 10 Foot main Tower Section consists of 7 bays spaced approximately 15.75 inches. The ROHN 20G Product Line is intended for Home TV Antenna use, to be installed in a Bracketed Configuration, whereas the ROHN 25G Tower line can be Free-standing to certain heights considering antenna and wind load, and guyed up to 190 feet. A ROHN 20G 10 Foot main Tower Section could theoretically fit on top of a ROHN 25G Base or Section, whereas the 25G will not fit on top of any ROHN 20G component. Understand that we sell only ROHN 25G Tower sections and components, we do not sell any 20G parts (not that there's anything wrong with the ROHN 20G Product Line, it's simply that the diversity of our Customer demographics are best served by the ROHN 25G Product Line!). This by no means is an endorsement of "Mix and Match", other than ROHN represents that all ROHN 25G and 20G "Accessories" are the same and completely inter-changeable (emphasis on the word "Accessories").
Most Restrictions Allow for 40 feet of Height without the Necessity of Guy Wires, Anchors or Braces. However, No Tower is self supporting during construction! Always use temporary guys on the top most section, and install permanent guy wires as soon as a guy point height is reached.
