Thanks Bob, washers are on my shopping list! I need butterfly nuts too, but can't get standard threads in France. Thankfully there is the Internet!

Joel, make sure you tell Dale P. Where you heard about it ;-) maybe he'll send me another antenna to test! I bought this one...

Great video Gil,

I contacted Dale Parfitt about your antenna after watching your video and to get pricing and some info. He got right back to me with this:

These antennas are an entirely different design from the classical
  shortened  half wave loops.
   Omniangles use an electrical length LONGER than a half wave and an
  isosceles  triangle shape to synthesize a perfect omnidirectional pattern
  (within +/-
   0.5dB). The square and round loops have an elliptical pattern with front
  to  side ratios of 5dB and more! We hope to soon have plots taken at the
  Florida  Motorola anechoic chamber of all of the commercial "omnis" on our
  site
   Our largest clients are commercial and military. As a result, all of our
   hardware is stainless, all metal surfaces are either polished or
   jitterbugged. The connectors are silver/teflon. The Omniangles are the
  only  commercial series that have a built in balun and do not require an
  insulated  mast in order to prevent mast/feedline radiation.

I think I will be buying one of these as soon as I can afford it. I just bought a HF Mag Loop, so I have to recover from first.

Nice vid Gil.

I see what you mean about the U-bolt not having threads that go down far enough.  Of course you always have the option of using a stack of washers under the nuts.  I had to do this once and I glued the washers together so I wasn't always fumbling with them.

At first I thought it was a Moxon and wondered what the Omni part was since a Moxon has a big front-back ratio.  I never gave much thought to the difficulty of doing a horizontally polarized omni, but it can't be done with something as simple as a ground plane vertical or J-pole like you can use for a vertically polarized omni.  This is clever, and small.   Then I thought "I wonder how hard it would be to convert it to a Moxon.", but I looked it up but the square pipe would need to be about twice as long. 

BTW, in the background I think I see several masts ranging from about 3M to 6M tall on houses.  Are there a lot of radio operators there or are they for TV or something else?

Licensing / Re: Getting License or NOT
« Last post by gil on July 22, 2017, 04:40:19 AM »
Hello,

You might be able to transmit under your call sign using a prefix, but the US license is VERY easy to get. I passed my Technician, General and Extra exams in the same session, for $15! I bought the three books from the ARRL and studied one chapter per day in each book. Since the chapters are on the same subjects, you study three chapters per day on the same subject from the three books. You can find the dates and locations of the exams on the ARRL web site. The people doing the exam are ham operators authorized by the FCC. The exam usually takes place at a local radio club.

When I lived in Florida there was a LOT of activity from every state, and a lot of Morse code. This was only two years ago. I am surprised you don't hear much... Maybe your antenna or you are not listening in the right places.

I'd say that you should get the US license. This way you can practice. You should be hearing lots of traffic. Make sure you listen on the right frequencies and check your equipment.

Where are you located?

Gil.

Licensing / Getting License or NOT
« Last post by BrankoBem on July 20, 2017, 12:57:37 PM »
I was Ham radio operator in former Yugoslavia 30 years ago. I am still holder of Class A license in now Croatia 9A6LAM. Class A is license is to operate on all amateur bands with power up to 2 Kw. My Morse code speed was around 150 character per minute. They do not measure WPM over there. I almost completely forgot Morse code but it will come back with practice. Couple Years ago I decided to go back to Ham radio and I purchase Yaesu FT-857D transceiver and antennas. About 1 month ago I had to replace roof on my house and that was good time to install antenna. As far i know I cannot transmit without US license but I can listen. What disappointment. Except some RTTY on HF and some chat on VHF and UHF there was 0 activities on the bands. Not even on CB. No single Morse code that you can hear. 30 years ago you had hard time finding free frequency to transmit. I am wondering should get US license or NOT? Did I just waist money buying Ham equipment? Is it going to get better? If I do I would like to get Extra license. But do I have to go thru 3 steps Technician, General, Extra? I do not know even how to get to exam. Who is doing exam? How to get to people who are doing exam? I would like to get opinion what should I do. Please do not tell me that license is good in case of big disasters. I case of disaster you do not need license to transmit, plus we are not going to have that big disaster. If we do it is not going to be like in the Hollywood movies. Please help me with my dilemma and go to band and start calling. Only if you start calling as much as you can  Ham could come back. It is long shoot.

I would love to buy your 817, but I have no $$$ right now:-( I saw it on QRZ also.

  The cap of a pen is a great idea.

I attach to the wire a small piece of paracord with a Hanged knot to fit in the físhing pole, It gives no surprises with the mountain high wind.
