Time to bring those old CB radio antennas out of storage. Rory

With the lowest frequency on the HF band being 1.8 MHz, 80 foot is more than easily justified. http://www.dx-antennas.com/Height%20versus%20take%20off%20angle.htm Thank You, Brian Webster 214 Eggleston Hill Rd.

The normal rule of thumb is that if your tower did not blow over in the last big storm the antenna was not big enough. You could stick up a 1.2 GHz omni about the size of your thumb, or even a 10 GHz beacon that would be even smaller. 2 meter quarter wave whip is 19 inches and could be mounted on the side of the tower.

They do not yet have their amateur license but working on it. By placing an amateur radio antenna, the FCC mandates the local government to let them put up an 80 ft. tower. I am not certain there has to be any kind of justification of what type of antenna (or anything else) but just in case, it would be nice to have some insight. Since I am not an amateur license holder, I am not knowledgeable on the subject. At the “end of the day” once the tower is erected and final inspection is completed, then the customer will also put up an ePMP Force 200 to get service from us at 6miles away.
