I was just given a 3 element beam antenna. Some simple estimated measurements (~16+ ft elements) lead me to believe it is a 10 meter antenna. It does not have any traps or coils. It has a gamma match but I might have to work with/repair that. Is there a good source of information on gamma match specs for a 10 meter 3 element beam? If there is, I can make sure I'm in the ballpark. I take it that if you don't use one, you'd have to settle with the impedance mismatch or you'd have to trim the antenna, right? If any of you have used a 10 meter, 3 element beam before, what were your results? Have you used one recently when the band was open? What type of gain can be expected, 7 or 8db over a dipole? I have a G5RV, which is not a great antenna for 10 meters, but I have made some fun DX contacts. I also have a vertical CB antenna that I messed around with on 10 meters and had fun talking to Asian stations. I'm just experimenting right now and everything is temporary. My G5RV is in an inverted V configuration right now with the apex at a measly 25ft. The small vertical is at 6ft above ground. The best I could do right now with the 3 element beam would be about 20ft above ground. If I get this 10 meter 3 element beam working right, what difference if any could I expect over the G5RV or the small vertical?
