The reflector is at one end of the boom, followed in order by the driven element and the first, second and third directors. Potential uses for 70cm antennas include FM and repeater work, long distance SSB contacts, digital modes and satellite The 2 Meter version of this antenna could be mounted up in the clear, and "sited" on the center of Rochester. This project was devised some years ago due to the need for 16 identical VHF antennas used for a CADF (Commutated Antenna Direction Finding) system for the 2-meter band. The formula of 468/freq gave me the length for the driven element and around 5 The Yagi was designed using Martin Meserve’s VHF/UHF Yagi Antenna Design tools. A fellow Ham recommended that I try building a 2 meter / 70 centimeter vertical dipole antenna. Jun 26, 2020 路 If you need about 11. Of all simple vertical antennas over ground, the 5/8 wave radiator has the lowest angle of radiation, however the base of the 5/8 antenna presents a relatively low impedance, not the high impedance offered by the 1⁄4 wave stub. Go with a 3 element yagi for 2M SSB/CW (works well for FM also). This means that you can experiment without fear of wasting much material. I decided to go for a dipole driven element fed by a “Bazooka Balun”. Listed under the Antennas/2M category that is about Antennas for 2 meters band.

The tape measure antenna is a "home brew" 2 meter antenna made out of PVC pipe and a steel tape measure. While the gain won't be "up there" with the big tri-banders & the like, a useful amount of gain can be realized without breaking the bank. If antenna is expensive no problem home brew it yourself. All you need is two rabbit ear antennas from Radio Shack, two CATV baluns, four feet of 3/4″ CPVC pipe with one tee, and a bit of time. While calculations Design Details and Drawbacks The element lengths and spacings are a combination of info from the ARRL Antenna Book section on 2 meter Yagi antennas, and from experiments with a field strength meter and different length elements and spacings. A fun little project I did over a couple of days was making this little 6 element yagi for 70cm. ) for any radio or satellite use that uses 2-meter frequencies. I came up with the idea after building several simple outdoor 2m/70cm yagi-style beam antennas (using a 1″x2″ wooden boom for support) and realized it could be adapted for indoor use. I recently bought a IC-705 and would like to try 2m ssb in addition to fm. 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. YOUR OWN TWO METER YAGI WHERE TO START! By Dave Clingerman W6OAL A step by step instruction on the creation of a four element, horizontally polarized, two meter Yagi you can build yourself. I re-engineered the mechanical design to be super lightweight and super easy to build. Paul Athersmith takes us through the complete, step-by-step design, construction, testing, and use phases of this compact portable 2 meter antenna. It is often used for Yagi directional antennas. 73, Jaakko OH7BF/F5VGL OH9FZU 17 February 2012 18:53 15 In reply to G8XYJ: …you could visit Nuxcom website and their Duoband Yagi 2m/70cm with 4 Elements on 2 m and 5 Elements on 70 cm and one Feedpoint Version 1: Ultralight with 3,2-mm-Elements Version 2: With 8- and 10-mm-Elements (see down), built by SQ9VPA Strangely, the antenna still works on 20M and 15m but the performance is off to say the least. It used ezNEC2 for analysis. Jun 27, 2018 路 Homebrew 5 elements yagi for 2m at 145Mhz VHF great performance and lightweight construction make it a suitable long distance point to point contact antenna This video clip describes my build of a four element 2m portable amateur band Yagi antenna. Unless you need very high gain the antennas are small. This is my favorite antenna for mobile transmitter hunts, as it doesn’t stick up as high above the roof as a yagi (for vertical polarization). My sources of inspiration were: Homebrew Satellite Antenna, G6LVB Cheap Yagi Antennas for VHF/UHF, WA5VJB The Microduplexer, KI0AG Kenwood, Yaesu, Icom, MFJ, Yaesu, Alinco radio transceivers and receivers mods homemade radio transceivers and receivers homebrew HAM radio transceivers and receivers Converters for HF, VHF homebrew antennas yagi, vertical HF, VHF shortwave antenna's, projects and schematics HF HAM Radio in general Radio basics and electronical easy to build . In this tutorial i show you how to build a Yagi antenna for the 70 cm band (430-440 MHz). Best of all, there`s no power-robbing matching network or finicky tuning adjustments because it`s CAD optimized for fullband operation 6 days ago 路 3 Element Yagi for Six meter band Plans for 3 elements beam antenna and gamma matches G4CQM Homebrew VHF Yagi antennas Homebrew VHF Yagi 50MHz 144MHz 432MHz 1296MHz 2320MHz 6M 2M 70CM 23CM 13CM Yagis The 2-Element-HB9CV-Beam The HB9CV-Beam is a 2-Element-Yagi with two driven elements and was introduced by Rudolf Baumgartner, HB9CV in the 1950ies. I am launching an ambitious homebrew satellite antenna build project and need design advice. So I make do with a long, thin random wire that works nicely as long as the New England wind, snow and ice don’t conspireRead More Jan 2, 2024 路 The spring will recoil into the case and the tape will be ready for trimming. So I decided to combine the best ideas of a few existing designs and add my own twist to it. These antennas are large, cross-polarized yagis. May 4, 2025 路 DX-ing and EME 2m 11elements Low Noise LightWeight Antenna 2m11DXL. gud luck 73 Pete WA7JTM kk6tmn 3 August 2016 00 A portable 2-element VHF yagi Article by K3MT Here’s a simple Saturday project: build a portable VHF yagi antenna for 2 meters. I simulated the same dimensions with 8 mm and 6 mm e 6 days ago 路 Folded Dipoles for VHF/UHF Yagis Make your own VHF/UHF folded dipoles from aluminium tubing. 250mhz as the center frequency which is in the middle of the SSB portion of the 2 meter band and according to Yagi Beam Antenna for 2m This 2m yagi uses design data from DK72B’s excellent yagi website. It needed the have the highest forward gain possible with the fewest parts and no matching network. DIY 5$ Portable VHF Yagi Antenna for the 2 Meter Band (144-146 MHz) by F4HWK: In this publication i explain how to build a very light weight, cheap, easy to build and deployable in 30 seconds portable VHF antenna for the 2 meter band. Then, at the Rochester Hamfest (at RIT in 2013 I think), I ran across an old Radio Shack scanner antenna (Model 20-176, thanks to W3OAB for identifying it after I bought it). This sketch shows a semi-exploded view of the antenna. Mike (M0MSN) takes us step-by-step through the building, testing, and use of this impressive VHF antenna. Feb 7, 2017 路 The 2 Meter band tape measure beam antenna is a 3 element Yagi with about 7. 3000 MHz at a drive impedance of 50R. The Reflector and the Driven Element are a project for a home made 5 element yagi uda antenna for 2 meters covering 144 148 mhz band by n1bmx. Version 4 of the portable beam, the ‘PegTenna’! This page contains construction details on a 2 metre 144MHz VHF Yagi beam antenna, designed for portable use. Dec 18, 2012 路 One of my favorite things to do is talk with other ham radio operators through satellites or the International Space Station (ISS). The low impedance of the driven element also reduces efficiency.
