Click to enlarge144MHz 2m Portable Yagi VHF Beam Antenna by MUKD
This page contains construction details on a 2 metre 144MHz VHF Yagi beam antenna, designed for portable use.

Click to enlarge144MHz 9 Element (DK7ZB) by DF9CY
Around Christmas 2003 I decided to give 2m (144 MHz) another "kick". I have looked to the GT tables provided by Lionel Edwards VE7BQH and found the DK7ZB 9 ele to be a good antenna for my purpose.

Click to enlarge144MHz Longyagis (28-Ohm) by DK7ZB
High gain, good pattern and acceptable bandwidth. These aims can be realized with a radiation-resistance of 25-35Ohms. Because the 28-Ohm-feedpoint is very simple to match, I use this impedance for my long Yagis.

Click to enlarge2 Meter Backpack Quad Antenna by KGZZ
This 2 meter 3 element cubical quad antenna is small, light weight and portable. A backpack antenna that is easy to put together in just minutes and parts store inside the boom making it ready for travel or storage.

Click to enlarge2 Meter Moxon by PA1EJO
After the most recent fox hunt I thought that a smaller antenna would be helpful, so I went for the moxon for 2 meter, material used: 32 mm PVC tube etc, coax cable, glue, tie wraps, 4 mm brass bar...
https://pa1ejo.wordpress.com/2018/07/07/2-meter-moxon/

Click to enlarge2 Meter Quad PVC Pipe Antenna by KGZZ
This is a different way of using PVC pipe to build a 2 meter cubical quad antenna. Instead of an "X" style spreader this antenna uses an "H" shape spreader.

Click to enlarge2 Meter Turnstile Antenna by WB8ERJ
A Turnstile antenna with a reflector underneath it makes a good antenna for space communications because it produces a circularly polarized signal pattern and also has a broad, high angle pattern.

Click to enlarge2 Meter Vertical Moxon by WB5CXC
Here is some data on a 2M vertical polarized antenna I built this week. I'm not sure about the gain but the front to back ratio is very good and conforms to the model.

Click to enlarge2m-SSB/CW-12.5-Ohm-Yagis with extrem high gain and small bandwidth by DK7ZB
For Yagis with a boom of >=1,5 lambda you should prefer 28-Ohm-Yagis, they have only 0,05dB less than the 12,5-Ohm-types with the same length, but have more bandwith and are less critical.
http://www.qsl.net/dk7zb/2m-port-SSB/construction_details.htm

Click to enlarge2m-Yagis with the 28-Ohm-DK7ZB-Match by DK7ZB
Short means, that these Yagis have not the length for EME-groups... All Yagis have a stretched dipole (the lengths in the tables are from tip-to tip), for the details see 'The DK7ZB-Match for Yagis'.

Click to enlarge3 Element 2M Light Yagi by WB5CXC
I used aluminum welding rods to build the 3 Element Light weight yagi. The welding rods are 1/8 X 36. You will have to join two rods together to make an element. That was a problem, I decided to use a mechanical joint.

Click to enlarge3 Elements VHF Yagi antenna by SV1BSX
The antenna is being constructed by using 15 x 15 mm aluminium boom and I have used for the elements tubular aluminium rods of 8 mm diameter. If the elements are placed directly to the boom.

Click to enlarge6 Elements VHF Yagi antenna by SV1BSX
The maximum forward GAIN is almost 11.9 DBi (abt 9.8 DBd) into 2 m. Band. With almost 10 DBd gain, we have an Effective Radiation Power (ERP) 10 times greater of the tranceiver maximum output (without Coaxial-Loss).

6m/2m/70cm Yagi Antenna Built from Old TV Antenna by KGZZ
This turned out to be a great little antenna. It works the 6 meter, 2 meter and 70 centimeter bands. You can use one common feedpoint or two seperate feedpoints depending on how you would like to connect this antenna to your transceiver.

7 dB for 7 Bucks by WBCMT
Need a 2-meter beam antenna, but you're short on cash?
You can build this antenna for the cost of a fast-food meal!
http://www.arrl.org/files/file/Technology/tis/info/pdf/9304054.pdf

Click to enlarge7 Element VHF High Gainer by VU3NSH
This antenna contains 7 elements, perfect for the 11db gain with a front-to-back ratio of 20-25 dB. You should need a matching network for this Yagi. I chosed a gamma match made from a piece of 3/8" aluminium tubing 7.25" long with a piece of RG-8 coax 7" long.

A portable 2-element VHF Yagi by K3MT
Here's a simple Saturday project: build a portable VHF yagi antenna for 2 meters. 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.

Click to enlargeCheap Yagi Antennas for VHF/UHF by WA5VJB
These antennas are relatively small, easily constructed from common materials/tools and have surprising performance. The feed method is greatly simpified by directly soldering the coax to the driven element.

Click to enlargeDK7ZB yagi for 144MHz by PA3HCM
After the somewhat disapointing results of the DJ9BV antenna, I decided to try another model. This time I selected a 9 element DK7ZB for my test. I already bought some square alu bars, each 250cm tall. Since the 9 element DK7ZB is 5 meters tall, this should fit perfectly.

Click to enlargeThe Tiny 2 by W4SAT
The "Tiny 2" is a great little 2 meter beam. It has some really interesting properties and it is a fantastic first time antenna project for the beginner.
http://www.qsl.net/w4sat/tiny2.htm

Click to enlargeThe Tiny 2+1 by W4SAT
As in the case of the 'Tiny 2', the front-to-back was sacrificed in order to squeeze as much gain as possible from the antenna.

Click to enlargeURGT VHF Cardioid antenna by VU3NSH
This unusual antenna is having only two things; One is a rectangle loop and the other is a reflector. It will produce a CARDIOID pattern (heart shaped). Two ground plane array with a proper phasing will produce the same pattern but it needs a phase difference of feedline.

Click to enlargeVHF DF Antenna by SMVPO
Here is a VERY narrow nulling VHF Direction Finding (DF) antenna that can be folded up in the back of the car, then you can leap out, assemble it and take a 'fix' in something like 10 seconds.

Click to enlargeVHF Test Antenna by SMVPO
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.

Click to enlargeVHF/UHF Wideband Portable Dipole by ON6MU
As everybody knows a dipole has about 3dB gain over a quartre wave antenna, is why my preference went to a simple dipole. To make it portable I used two identical telescopic antennas of 80 cm slid out and only 14 cm when pushed in.

Click to enlargeVHF-UHF Portable Yagi-Uda Antenna by XE1MEX
Since it is very difficult to get a commercial VHF-UHF portable antenna in my town, I decided to build a homebrew antenna as I did it in the past with most of my old HF and VHF antennas.
