I ordered one. Now, he says u need at least 50' of coax, more is ok. He also say you need some kind of choke so rf does not get in the shack.
Where does the choke go? On my beam the choke goes at the feedpoint on the antenna. on this end fed antenna does the choke go at the antenna feed point or does it need to be at least 50' down the coax or just before the coax enters the shack? Is the 50' part of the coax supposed to radiate? Next he says he put a ground lug for those who want to use it. The feedpoint will be aprox 50' above the ground on a tower. So, ground it to the tower leg, or run a separate insulated wire to the ground and ground it, or connect it to radials on the ground or elevated. If elevated they must be high enough to walk under. That would put them about 43 feet below the antenna and they can only run in a 180 degree path some as little as 25' others as much as 50' or do they all need to be the same. I have a 500' spool of 14ga. and I can use it all if this will help my signals. Also the radials will not be under the antenna rather on the oposite side of the tower since the antenna runs over the house for the first 60' then over open yard. Radials have to be in the side yard away from the house. So many decisions. I really want this to work as well as possable and since I have to pay someone to install if for me I want to do the job right the first time.
I only need this antenna to work on 160, 80, and 40. I have a beam at 53' for 20-10.
