2 Meter Ground Plane Antenna

Because of the move from Laie to Hau’ula a couple of weeks ago, I had to take down my antennas and put them back up again in the new location. The first antenna to go back up and into operation is a 2 meter ground plane antenna.

I took the original idea for the antenna from an article on hamuniverse.com. I bought some 14 gauge bar wire and some small bolts and nuts from Lowe’s along with 25′ of RG58 coax and an SO239 panel adaptor from Radio Shack. I built it as described in the link.

I threaded the coax up through a two foot section of 1″ PVC pipe from Ace Hardware. I used Gorilla Duct Tape (also from Ace) to hold the SO239 down on the top of the PVC pipe. Since the coax has PL259 connectors on either end, it mated up very nicely with the ground plane¬†antenna.

The PVC pipe is attached to a 12′ painter pole that I bought at Lowe’s for this purpose. I drove a 1 3/4″ piece of PVC pipe (also from Ace) into the ground so that about 18″ were above the ground and stuck the bottom of the painter pole into the PVC pipe and the attached the pole to the fence. It has very low wind loading and has stood quite firm during the recent tropical storm that came through.

This antenna is one of four antennas going up at my new address in Hau’ula. This antenna is connected to a Motorola 2 meter radio operating simplex on 147.450 Mhz attached to the AllStar network via a Raspberry Pi. See the AllStar category for information on that setup. The antenna has been an excellent performer. Together with the 20 watts output from the Motorola radio, I have excellent coverage throughout the Hau’ula and Laie area.

I recently discovered this podcast and listen to it on my iPhone. The recent two Workbench segments sold me on the podcasts. They were about bench power supplies (I bought one based on this podcast) and the first of a two-part series on oscilloscopes. I’ve always been fascinated by ‘scopes and have a very incapable one that uses an Android tablet. I’ve also got two other (very cheap) DIY kits that I haven’t put together, yet. I’m not expecting much from either of those kits, but I should begin some actual learning guided by what I’ve learned in the oscilloscope series.

Cale Nelson’s episode on ham radio satellites was excellent. I’ll be listening to that one again when I get a capable antenna and can actually try to work someone on a satellite.

I’ve started doing some kit building and antenna experimentation. So, it’s time to start documenting what I’m doing for a couple of reasons:

  • At my age remembering what I did yesterday is rather iffy….!
  • If I write it down, then I don’t have to remember it!
  • Someone else may figure out how to do it better and with fewer mistakes.

So, here goes. I’ll build an “about” page, get the menu set up, and then from time to time write up what I’ve been doing.
