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,
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!
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
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
