Taking the Guesswork Out of Quotes

At Rohn Products International L.C. (RPI), we strive to meet our customers’ needs and expectations during the quotation process as quickly as possible. Sometimes, though, our customers may not understand the options available to them and/or they provide additional information after the fact that impacts design and engineering, as well as the types of accessories and add-ons necessary for the project.

We recognize that filling out forms is not everyone’s favorite activity, so with that in mind, we offer a mini-tutorial, of sorts, that explains the line items of our Quotation Questionnaire form.

An RPI representative is just a phone call away to answer your questions and serve as your consultant to find the best and most cost-effective solution for your project. See the contact information on the quotation form.

1. Quote is for: Do you want ROHN to manufacture your tower or pole only? Or would you like us to install it as well? We assume the site has been prepared and is accessible for delivery. Tell us if this is not the case.

1A. Design assumes: We also assume that soil and rigidity of your site meet EIA standards, and that, in the case of a guyed tower, the site is large enough to accommodate an 80% guy radius (the distance of each outer guy wire foundation (anchor) from the tower center equals 80 percent of the tower height).

2. Foundation Installation: Who will install the foundation, your contractor or RPI? If RPI will build the foundation of a tower, please provide a sketch or azimuth of one leg showing its directional orientation.

If no sketch is provided, we will assume the north leg is 0 degrees. Note: Azimuth is important when a structure supports directional dishes.

3. Structure Type: Do you need a guyed tower, a self-supporting tower, or a roof-mounted tower?

4. Structure Type: (cont.) Or, do you need a tapered or flanged pole? If you are unsure about the type of tower that will meet your needs, or if a pole can meet them better, just give us a call.

5. Structure Height: The height is the customers decision; however, the design and engineering specifications for the structure may be influenced by local building codes. If local codes do not apply, we design in accordance with EIA standards.

6. Base of Structure: Will the tower or pole have its foundation on the ground? Or will it be roof-mounted? In the latter circumstance, tell us the height from ground to the roof-mount location. We need to know this to factor in wind variations at different heights.

7. Design Load: The load or stress on a structure is influenced by its height, the equipment mounted to it and the weather conditions of the structure’s site/location. By design load here, we refer to environmental factors of wind and ice. Do you have specific requirements for design load? Identify your requirements by selecting Basic, Uniform, 3-Second Gust, Ice or Other.

Basic (Fastest Mile) refers to wind speed averaged over the shortest time for a mile of wind to pass an anemometer (example: if the shortest time for a mile of wind to pass an anemometer is 60 seconds, the fastest-mile speed would be 1 mile per 60 seconds or 60 mph). This wind speed is escalated as you go up the tower.


Uniform refers to load factoring of wind as constant (the same) from bottom to top.


3-Second Gust refers to load factoring based on average highest wind speeds measured in three-second gusts (typically higher than fastest-mile wind speeds).


Ice refers to the weather conditions for ice at your site. Is ice a factor we should know about?


Other refers to special loading condition.

8. Operational Load: We will abide by EIA standards for twist and sway stability (50mph basic) unless you tell us otherwise. Note: Extra stability may be important to ensure reception and transmission for line-of-sight dishes. Rigidity requirements at higher wind loads will result in a more costly tower and larger foundations.

9. Step Bolts or Climbing Ladder: Depending on the type of structure desired and its height, step bolts or an inside/outside ladder may or may not be appropriate. Consult your RPI representative before specifying a choice.

10. Safety Device: Our ROHN-Loc product is an all-in-one safety climbing device that includes a harness and all hardware to attach to the tower. We recommend it! However, if you choose another safety device from another supplier, please describe it. We need this information to allow for any design variations to accommodate an alternative device.

11. Aircraft Warning Lights: The ICAO will specify required lighting for your structure. We offer many lighting choices and where the ICAO grants discretion on types of lighting, we will be happy to consult with you about options.

12. Paint: The ICAO requires structures with red lights only to be painted orange and white. Let us know if you want your structure painted in the factory or if you want us to supply paint for site painting. We can also paint your structure with special colors, based on your preference.

13. Vertical Waveguide Support: Some customers desire vertical cable ladders; others do not. Ladders are appropriate for self-supporting towers. Brace brackets are commonly used on guyed towers.

14. Location of Vertical Waveguide Support: Where do you want your cable to run? The outside face location is often less expensive than back-to-back or down the center. We will be happy to consult with you on the best location.

15. Horizontal Waveguide Bridge: Tell us the distance from the structure to the building so we will know how many feet of cable bridge are required to make the electrical connection at the equipment enclosure.

16. Lightning Rod Required: Tell us whether you want a lightning rod supplied by ROHN; also indicate the size of the downlead wire, if required.

17. EIA Grounding: We will ground your tower in accordance with EIA standards. Any additional grounding requirements must be specifically stated.

18. Antenna Information: This data is very important. We need to know the quantity, type, location and proposed mounting of all antennas to appropriately design your structure for load and capacity. Provide the model numbers of all antennas (or their specific dimensions) and their manufacturers. If microwave dishes are used, specify their frequency. Let us know if you want RPI to supply mounts for these antennas.

19. The following is required for special foundation designs: This is site-specific data. Unless you provide a soil analysis, we will assume normal soil as described by EIA, and design accordingly.

20. Additional information: The more you tell us about your project, the better the outcome of the quotation process.

21. Purpose of Structure: This is useful information for RPI about the needs of our customers.

Getting a quote from RPI is really a straightforward process; the more you tell us about your needs, the more you get in the form of a comprehensive cost analysis of your project. We are here to review your needs, line by line, if necessary. We promise to give you our best quote in return.
