Makea 4″ X 4″ X 1/8″ plate of aluminum for your boom to mast plate. Mount four appropriate size "U" bolts and saddles on the four edges of the plate. Mount the boom to mast plate at the center of the boom. Make the elements horizontal and attach the assembly to a mast 5 or so feet above ground. Finished Antenna. Theantenna is basically a quad opened up on the bottom. This up and over, over and down design had been used in HF wire antennas. The antenna acts like a stacked pair on the vertical and a standard yagi on horizontal. The prototype for 2 meters made its first contact of over 200 miles while lying upside down on a picnic table. Whenusing multiple yagis, they should ideally be mounted at least 10 ft apart and not pointed at each other to prevent any interference. Then use a signal splitter to combine the two antennas into one cable that can be attached to the amplifier. Because a yagi is a powerful antenna, there may be situations where it can overpower the cell
buildantenna project for 2 meters. I have not seen it on the internet so here it is for you to try! I personally have not tried this antenna but it should work fine if you follow the very simple directions! It can be built as is for 2 meters, or you can try it on other bands or frequencies with the formulas provided by me below.
Repeatprocedure until lowest SWR is obtained and mount yagi on your mast, pole, tower, etc in a horizontal position relative to the ground for 6 meter SSB operation. The SWR in the final operating position may vary slightly but not enough to worry about. The measurements on the picture below may be very hard to obtain perfectly, but don't Theresource is currently listed in a single category. The main category is Antennas for 2 meters band that is about Antenna projects for 144 MHz. This link is listed in our web site directory since Monday Jan 16 2017, and till today " Lightweight 4 Element Yagi for 2 meters " has been followed for a total of 807 times.
Thisantenna is a plumbers dream. Most parts are available on the World Wide Web or at some larger hardware stores. This two-element Cubical Quad antenna is designed for use on either the 10-meter ham band or the 11-meter Citizen's Band. When all was said and done, my SWR readings were 1.3 to 1.7 on the 10-meter band.

DIY5$ Portable VHF Yagi Antenna for the 2 Meter Band (144-146 MHz) by F4HWK Step 1: Materials and Tools. All you need for this antenna are 3 pcs of 4 mm diameter threaded rods, a PVC bar with a Step 2: Dimensions. All dimensions are given in mm on the first figure. The antenna is a Yagi type 315. Table from the Electrical Conductivity of Metals. With copper being twice as conductive as aluminum and 6 times more conductive than steel, it makes an excellent choice as an antenna material. The increased electrical efficiency means more of your RF energy will go up and out the antenna and not be trapped, creating heat energy. A146 Mhz J-Pole Antenna. A 2 meter (146 Mhz) J-Pole antenna that is inexpensive, and easy to build. A J-Pole for 2-meters and 70-cm. An Easy Dual-Band VHF/UHF vertical Antenna made with a TV twin lead and coax cable. Simple j-pole antenna for 2 meter. xyU69H5.
