Buildingand experimenting with antennas can be an interesting part of the radio hobby. Here we have collected some links to building instructions for 11m antennas on the Internet. Contains dimensions for a 3-element yagi and a 4-element LFA Yagi for 11 meters. There is also instructions for gamma match construction and pictures of a J-pole Theantenna mast mounts to the frame's center pole with a 1 1/4″ x 3″ U-bolt and some short sections of 1/2″ x 1″ iron or aluminum channel. Cut the channel to about 4″ in length. Mike(M0MSN) takes us step-by-step through the building, testing, and use of this impressive VHF antenna. Here are some of Mike's comments: "The construction of a shop purchased, ZL Special 7 element Yagi antenna for the HAM Radio 2M band. This no frills antenna boasts a 11.5 DBd Gain, is simple to build and works straight out of the box (once TheFolded Dipole is commonly used by itself and in many types antennas. A Folded Dipole feed is common in VHF/UHF Yagi antennas and as the main element in many HF antennas. The Folded Dipole is a combination Split Dipole feed element plus a unbroken Impedance Transformer element. The two elements are connected together at each end. This arrangement provides some mechanical and electrical advant Theantenna is shipped almost completely assembled. All you need to do is install the 1/2 inch Aluminum tubing at both ends of the 10 Meter and 6 Meter antennas, adjust them to the proper length and tighten the hose clamps that hold them in place. The antenna is then ready to install on your vertical pipe and Rotator. 10N6RDB Radiation Pattern Herewe take a look at building a short, loaded dipole for 20 Meters, 14 MHz.In fact, this is going to be half of a 2 element yagi for the 20M band.L/C Meter TheYagi antenna is a narrow-band antenna designed to work only on FM channel. It has the best gain for its sizes and a correspondingly narrow main lobe (beam). Get flat 2 core ribbon cable about 10 meters or more depending (Generally used for TV antenna, in early days) to be used as feeder wire from the transmitter circuit to the antenna. ALoft-Yagi for Six Metres. An option for restricted and limited space, to operate the six meters band with an indoor three elements yagi antenna by Brian Williams. 4 el yagi for 50 Mhz. The EF0604S is a compact 4 elements yagi antenna plan for six meters band featuring 8.77 dBi gain and a front back gain of 17.89 dB. GeorgeHuffman builds a six meter Yagi.For the entire episode visit: Thegamma match. The Gamma match is the most used matching device used for yagi beams. A Yagi almost never has an impedance of 50 ohms. In other chapters i told that Gain, bandwith, F/B etc. all relate to eachother these figures are never all high at one point. A well designed yagi has for that reson an impedance around 20..25 ohms. 5Element LFA Yagi for 6 meters band. A Loop Fed Array Yagi antenna for 50 MHz featuring 11 dBi gain and 23 f/ b ratio. In this excellent page the author even includes a detailed drawing in DWG format, with element lenght and spacing measures, in a separa file a full list of material list needed to build this yagi antenna including source and AboutVHF Yagi Antenna with Gamma Match The resource is currently listed in a single category. The main category is Antennas for 2 meters band that is about Antenna projects for 144 MHz.

A 2 Element Direct Feed Yagi For Multiple Bands By Wb2vuo. Gizmotchy 10 11 Meter Beam Antenna Specifications. Yagi Antennas For 27 Mhz 11m. Howwell does the antenna perform across 10 meters. The following table gives free-space figures across the band. Add about 5.5 dB to the gain for a height of about 1 wavelength. Modeled Performance of the 4-Element Wide-Band 10-Meter Yagi Freq. Gain F-B Ratio Impedance 50-Ohm Hi I want to build a yagi antenna for use at around 34-42 Mhz, but if it has to be narrowed down, more like 35ish. When using the calculator mentioned, it states the overall length would be 8 meters. Do you know of any way this could be reduced to something more man-portable(1.5-2 meters max). LGU0xpI.
