This page contains construction details on a 2 metre 144MHz VHF Yagi beam antenna, designed for portable use. Since an old 5 element version (v1) of my antenna was shown in the July 2011 edition of RadCom , a few people have contacted me asking for some information on how it was constructed.
This is a great starter antenna that can be handheld without being too unwieldy, and while it has modest gain it should be enough for you to accomplish both your goals with very little work. Note that the driven element is adjustable - you'll need to adjust that for the lowest SWR in order to accomplish your impedance matching.
27 Δεκ 2020 · This was a long project that worked out very well. The little antenna performs very well and should be durable enough to hold up through many moves. Link to the blog write up with design details:...
When it come to building this antenna I made the following requirements: Must be cheap to make ; Must be easy to assemble (possibly by children) Must fit into my tiny car ; Must not need special or heavy tools
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.
This page contains construction details on a 2 metre 144MHz VHF Yagi beam antenna, designed for portable use. It has successfully activated the following SOTA summits: G/LD-004 (Skiddaw), G/LD-021 (Robinson), G/LD-003 (Helvellyn), G/LD-001 (Scafell Pike) and G/LD-020 (Dale Head).
2 element six meter antenna The 6 meter antenna has two elements and is housed in ½ inch pvc tubing, using T connectors to form the yagi configuration, and another T is located mid- way between the two elements for support.
