I did measure the height and can get a max of 22 feet.does anyone know the impact this would have on a beam patterns or gains? this will give antenna height of 30-32 feet off sea level. I have some rattle can pink paint ready to make the beast pretty? :laugh: If the neighbors say anything I'll leave the Xmas lights on all year long and might add a few to the mast i HAVE ONE SHOT and want to get the most bang for the buck. Please keep info coming as I have not pulled the trigger yet on a purchase or design. I have seen these antennas in the web pages but not really taken a close look see. Thanks Homer and all for the input.they look to be a easy build and now this adds another antenna to study. I have limited space to put up much metal so I have looked at several antennas from long wires to skyppers to yagi beams to bobtail curtains :redface: Want to max the gain with as little metal as possible so the folks that live around me don't burn me out?!! I have room for a vertical but want to put up some type of beam if it is worth the effort. Surely someone on this forum has similar issues and has worked thru the BS with a HOA? I'm open to all ideas.in fact welcome all ideas or ? or something you have wanted to try out ? they just need to be able to get past the limits i have!! thanks to all thus far KEEP THE IDEAS COMING!!! PLS One forum memeber makes beams with the folded array but he's in europe!! shipping would kill me.he needs a US distributuion point and would most likely sell a ton of them. getting the best gain with the smallest impact for the neighbors. ![]() I had hoped to be able to use a short boom.10 ft or so and max the gain and fb ratio. Saw a post yesterday about making a folded element yagia from a maco that adds a little gain and FB ratio is another reason i lean to the Yagi. the antenna will show to the front yard but only about half the boom and front facing elements. The Boss thinks a yagi looks cleaner and I have to agree?.Īlso does anyone have experience with Siro 4 element vs a Maco 4? only 75.00 more, is the Maco worth the extra bucks? as far as quailty?Ĭlick to expand.Really looked at these antennas.issues are the added metal and fiberglas poles to paint and camo.I thought if i can get a yagi on the flat side it would not have as much visual impact as most antennas.not much more than a vertical. I have the most of the parts for a skypper but it has more Wife issues due to the wires and fishing poles etc. please add your ideas this forum has thousands of years of antenna experience and I would love to have a forum designed antenna if possible!!!!. The open bay/gulf of mexico is 200 yards east so a ground plane is not an issue but my trees and the surrounding trees and homes may kill any gain the beam gives? really need ideas?. The yagi will be nested in the yard? and neighborhood with trees all around:sad: 20 feet is all I can do on height?!!!! has anyone had to deal with much the same? any ideas Large trees will be 15 feet from the beam corners as it is rotated. 50 feet away.not a shock hazard but may cause interferance or pattern issues. At 20 feet the antenna is only 4-5 ft above the roof and also in line with some electric/phone cables appro. The absence of the controlling directors of a larger OWA design takes a bit of a toll, but performance is still quite good for a 40-metertubular Yagi.Įlement Material Strength of 40.000 (6061-T6)I have room to place a small beam such as a 3-4 element yagi short boom with out too much issue but the height would only be at 18-20 feet to the boom. Lost 0.75 dB of front-to-back ratio at the band edges. ![]() Gained about 1 dB of gain relative to the 3-element antenna. Nonetheless, the array shows sig-nificant gain and SWR improvements over the 3-element Yagi.Ĭlick the images to read the calculated specs. ![]() However, the Yagi lacks the 2nd and 3rd directors that lendfurther control to the operating characteristics. The overall boom length is abit over 3/8 wavelength. The secondary driver is 0.05 wavelength ahead of the fed driver. The reflector is 0.15 wavelength behind the driver. This OWA design uses reflector-driver-1st-director spacing that applies generally to OWAYagis. ![]()
