Has anyone ever used a Gizmotchy G31 3 element beam or the Jo Gunn Shogunn II beam? Is one better than the other? As in durability, signal, rejection, etc.,? Looking at purchasing a beam and space is somewhat limited. Looking at 3 maybe 4 element beam.
All comments are welcomed.

The Gizmotchy beam antennas are supposed to be better constructed. At least they say that in this area. I had a chance to buy a Jo Gunn and was told by some trusted ops that it wouldn't last one of our ice storms. For what that is worth.  |

What about performance of the Gizmotchy beam since you stated it is made up of quality construction?

My Jo Gunn has been up for around 15 years, & looks & performs like I put it up yesterday. It cost more but is heavy duty. The CRR round up hears me for years almost 80-90 miles away. The most wattage I run is 5-700 wiskeys! The square boom means elements stay lined up forever! The Jo Gunn is better constructed, but overpriced , in my opinion. 595 in South Jersey builds Jo gunn quility antennas, to MaCo specs! ...They kick a**!

I think someone over at Jo-Gunn was smoking crack when they made their gain ratings (especially that laughable "audio gain"). But they are well made, and will hold up to the elements (no pun intended)....... |

A lot of 11 meter antenna gain ratings are a load of bologna. Although I do love the 'audio gain' statements. ;D

One thing I noticed about Gizmotchy beams is when my friend "Panama Red" changed from vertical polarization to horizontal polarization on his three element Gizmotchy it did not make any difference in his signal strength on my vertical Imax 2000. When I switched from my Imax 2000 to the horizontal dipole I was running at the time his signal stayed about the same. The Gismotchy in the horizontal position appears to be transmitting either both horizontal and vertical polarization at the same time or something in between. There is a picture of Panama Red's beam on the Gizmotchy site. It is the one in the top of the tree. www.gizmotchy.com/Extremegizmotchy.htmlNight Ranger |

I may try the Jo Gunn II Beam to see if I like it. I appreciate the replies.

Both the Gizmotchy and Jo Gunn antennas are well made and should do you well no matter which one you pick to buy. I have a Gizmotchy up and has stood up to 80 mph winds, snow and ice.... and looks as good as they day I put it up new!

I mounted a 4 element Cush Craft in the top of a 75 foot oak tree in the 60's. I was much younger and built the beam in the top of the tree. It worked really well. After about 15 years , the part the antenna was attached rotted and all came tumbling down.

A beam is a lot of wind loading on a top of a tree. 15 years is pretty darn good.

With all the Tornado's and severe weather we had in Arkansas, I'm surprised it lasted as long as it did. I couldn't imagine what went on in the top of the tree during a severe thunderstorm. I bet it was really moving. The Cush Craft antenna was made of really stiff , large aluminum tubing. The swr never changed and the antenna shape never changed ( I thought it would bend)

Did you have a rotator on that beam?
