End Fed Half Wave Vertical Antenna




What do you think about this video?

videosbymike: This is the best $50 I have spent on ham radio gear. I have one in my attic and one for portable work. I have talk around the globe with both of them. Checkout my channel for videos using this antenna. Prepare for the worst and pray for the best, Mike

John La Sala: I bought this antenna for our condo. Installs within minutes mounted the unit underneath my awning and threw the remaining length of the wire over the roof top. My first contact was on 10 meters was Finland. This is a great antenna for coops and condo restrictions.

William Phinizy: The VSWR of your half wave vertical is NOT the 1.l, 1.4, etc. that you state. That's just the VSWR that your K-2's tuner resolves to. Put an SWR meter between the rig and the antenna and see what that reads. Moreover, your half-wave vertical is only a half on approximatey 14 Mhz. On 40m, it's a quarter wave and would need some counterpoise to be effective. But it seems to perform comparably to the OCF dipole..and that' s probably because of its low take-off angle.

Indrid Cold: There are a lot of people criticising this antenna. They are missing the point. The point is, this is an effective antenna for those on an extremely tight budget and have limited space, like myself. All I have is a small rig I found in the trash and worked a month replacing tiny components to get it to work on a measly 50 watts pep. The antenna is a J-pole made from small galvanized conduit. The coaxial cable was also found in the trash. The power supply is an Xbox 360 power supply with the end cut off. I mount this garbage antenna on the roof on a metal vent. 10 meters gets good VSWR. Good VSWR does not always mean good propagation. A dummy load has great VSWR. 10 meters is the only voice HF, I can use with my lowly 25 year old license. There is little sense in upgrading to general when I can not afford any equipment and my salvaged radio only has an 18 megahertz to 30 megahertz range. I am making a home made straight CW key from a mouse trap, cabinet knob, and old relay contacts. Poverty sucks!

Captain Ron: Thanks guys for the great demo..... I need a portable antenna and that looks great... 73's K2LOG..

Robert pendergast: I like it! N5JYW

WA2JSG: Nice video, thanks.

1redrubberball: It's apparent that you're happy with your antenna. However, it is not as efficient as it could be because you don't have a 50 ohm feedpoint Z at the lower end of the vertical. Your coax cable has several db of loss because the feedpoint Z of the antenna is very high, over 1000 ohms, possibly 2-5K, on 20 M. Antenna tuner in the rig only satisfies the rig. Put an auto tuner at the vertical and ditch the balun.

Steve Weiss: That reminds me. I made one of these end fed antennas a few weeks ago and forgot all about it. Guess I am going to have to test it out!

SpaceCityBeats: Thanks just saw the end of video with purchase info. Thanks for the info! 73

GoodPhotographDotCom: Great video....just bought the same antenna from the folks in Hawaii...was not considering a vertical approach but am now as a result of the video. I am curious how you attached the box to the mast? Wire ties? Also, loved the idea of the umbrella stand for the mast! Thanks!

SpaceCityBeats: Where did you get the pole?

SpaceCityBeats: I was under the impression that an FCC Amateur Radio License will supersede any HOA restrictions against antennas. Search youTube, I saw the News clip there.

SirLobsterman: would like to see it's performance in a horizontal set up, tree to tree. realistic demonstration to what a QRP hiker or camper might do on a mountain or even at a shore of a large lake or ocean, ect. . also, the 9:1 unun plans are easily found through google for free, like this one: http://www.m0ukd.com/Magnetic_Long_Wire_UnUn/9to1.jpg
