KA9EAK Mobile

I recently put together my first HF mobile station. It consists of the Yaesu FT-857D that I purchased two years ago and a Little Tarheel II antenna that I recently purchased.

My initial plan for a mobile antenna was to use a set of original Hamsticks that I obtained from various sources. These are very nice HF antennas but the primary drawback with them was that they are very long and I need to clear the parking garage at work and to do so requires the removal of the entire Hamstick assembly (base and whip) and then tucking this all away in my Corolla. This wasn’t the best setup given the parking constraint. A friend and fellow radio operator, Rick, AB9XI has used the same Tarheel for his mobile station for awhile with good results. So after a lot of consideration I purchased the Tarheel.

The radio, speaker, and mic clip are all mounted on a Plexiglass block which is in turn mounted on a gooseneck mount (AES MT-7) that I purchased from AES.

This makes it easy to remove the head and associated parts.

The Little Tarheel II is mounted on a Comet HD-5 mount:

The ground strap runs down to the main portion of the car body and is just a portion of the grounding\bonding that I’ve done for the installation.

I don’t have to tune the antenna anywhere near as much as I expected. For logging I simply use the Voice Memo app on my phone to record the particulars of each contact and then enter them into my log (N3FJP) when I get home. Rick, AB9XI runs a wireless network with his iPad for logging using the Piglet and Hamlog from Pignology. I’m not going to go that far yet.

In three weeks of operation this mobile station is performing quite well. In addition to a handful or more US stations I’ve contacted some DX stations as well:

KP4EML in Puerto Rico
VP9KD in Bermuda
OK2RZ in Czech Republic
WP2B in St. Thomas, VI

All on 20M and all with good signal reports. The distance to OK2RZ’s station is around 4600 miles though to be fair he has an antenna system that could likely hear a QRP station on Pluto! But still, 100W with a trunklid mount antenna on a Toyota Corolla motoring along in Wisconsin talking to people thousands of miles away is the amazing part of Amateur Radio.
