I'm assisting with designs for a new emergency management building that will have a 150' tower on-site. We are looking to place a HF antenna on the tower and want it to cover the 20, 40 & 80m bands. I need some advice for an antenna to be placed on the tower that has very high wind resistance. The communications company that is designing the tower needs to know what type of HF antenna we will be placing on the tower so they can get the specs on the tower to us. Currently I am only licensed as a technician, studying to take my general this year....so I'm not proficient in HF antennas. Thanks for any help.
