Hi gang, Could anyone recommend an individual or company that does tower and antenna installation in Southeastern lower Michigan? We are about 45 minutes SW of Detroit and are looking to contract a r
Hi gang, Does anyone have experience with cable-based safety climbing systems such as Trylon's Cougar system? http://www.trylon.com/safetyclimb/cougar_safetycable.asp Or DBI/Sala's "Lad Safe" system:
Hi Allen, group, We are also considering a similar group of antennas. Here are some thoughts, pros, cons: SteppIR 4-element, 10-20m: Highest gain (by 2.5 dB at most), highest cost, good reliability b
Hi Allen, There were some assumptions here, for sure--here are some specifics: The SteppIR gain was modeled by a 4-element NBS Yagi (optimized gain) and the LPDA was modeled by a 12-element LPDA desi
Hi gang, We are getting closer on our roof-top 40 ft tower design, but could really use some input on the following related issues: 1. How much mast to put inside the tower? We are going to use eithe
Hi Cameron, Our club recently installed the AlfaSpid al/ez rotator to position 2m and 70cm Yagis and a 60cm dish. It is working very well. Here is a link to Alfa Radio's site: http://alfaradio.ca/ind
Hi gang, Our club is clearing out some antennas we've picked up over the years to fund our ever-expanding tower project. Here is what we've got: ** Pickup in Ann Arbor, MI ** (1) New, Telex Hy Gain T
Hi Fernando, A 46 ft length of RG-8 (or other coax with 0.80 velocity factor) is a quarter wavelength at 3.75 MHz. If you connect one end to the antenna feedpoint (center conductor to vertical elemen
Hi gang, This could be a good opportunity for someone looking to put up a MonstIR soon, especially if you are close to Michigan... Our student club's (The University of Michigan ARC) tower project ha
Hi Gang, We are looking for a civil/structural engineering firm that has expertise in roof-top tower installations. Does anyone have any recommendations, or suggestions where to look (maybe an indust
Hi Gerald, Also be sure to include the wind area of your feedlines--they add up quickly! For example, for RG-8/LMR-400 (diameter 0.405"), 87 ft along the tower leg gives you another 87 ft x 0.405 in
Gang, For your enjoyment, here are some action shots of our new W8UM roof-top tower installation from 7/30/07. It is a 40 ft Rohn 55G tower on top of the 60 ft tall Electrical Engineering and Compute
Hi Carl, In a nutshell, we went with 55G for extra tower capacity and a safety factor. With the icing and wind conditions we had to meet with our proposed antennas at this height above grade, 55G had
