Experimenting with a 40M HamStick

Not long ago I stopped by the Ham Radio Outlet (HRO) in Anaheim, CA. As I looked around, I noticed a large wall display of HamStick antennas.

Actually, they are no longer referred to as “HamSticks. ” They are marketed by Shark Distributing, Inc. and packaged with their name. Regardless, HamSticks are legendary in the Ham universe.

I bought several of them, included an S-F20 and S-F40.

In the field, I screwed the 20M stick to a magnetic mount. Then I placed it on the roof of my 2004 Tundra and tuned it with my antenna analyzer. Tuning is easy. You slide the  whip up or down until your analyzer shows the lowest SWR. Once tuned, I marked the whip with a sharpie for easy deployment in the future.

I tested the 20M stick on several POTA activation’s. I was shocked at the great performance. I even had a DX QSO with a chap in Puerto Rico. Best $25 I ever spent.

Next up, the 40M stick. Hoo boy! This was a whole different story. I discovered numerous blogs and YouTube videos that trash this antenna as unusable. Many Hams say it cannot be tuned. Others say there is no way to “shorten” a 40M antenna to 44″ and get it to work.

Sure enough, I put the 40M stick on top of the truck and could not tune it. Not even close. I could not bring the SWR down below 2.5 no matter what position the whip was in. I suppose I could  have tuned it to the lowest SWR and used an antenna tuner (Z-11 ProII), but that spoils the convenience of a hamstick.

I found a YouTube video that recommended I loop the coax cable a few times around a ferrite toroid.  OK – why not?

What a difference! I was able to tune the antenna to an SWR of 1.2:1!  Now I have a very convenient way of getting on 40 meters in less than 2 minutes – without having to use a tuner.

The lesson here is – experiment. If something does not work, try to determine why. Then fix it or figure out a workaround.

My Favorite Antenna

Talking about antenna’s is always risky. This is one aspect of the Ham radio community where passions run high. Ham’s have strong opinions about antenna’s; most are biased towards antenna’s that meet their specific needs.

My POTA antenna needs are simple. I want an antenna that is easy to deploy, does not require a tuner, and does not cost a lot. It also must be a good performer.

Without a doubt, my favorite POTA antenna is the TennTennas made by NE4TN (Walt). The TennTenna is an EF 1/2 wave with a 49:1 transformer using a quality FT-240-43 toroid. You can find them on eBay. Walt hand makes each antenna, and they are of superb quality.

I prefer 20M when doing POTA activations, so I grabbed @33′ length of 14 gauge yellow  antenna wire (DXEngineering) from my parts box, and cut it to resonance using an antenna analyzer.

I get the wire in the air using a TN07 fiberglass mast supported by my custom flag-pole trailer hitch mount. I mount the TennTenna to the base of the pole using a velcro strap, run coax to my radio, and I am on the air.

To give you an idea of what the TennTenna can do, check out the below map of contacts I made during a recent POTA activation (US-3559).

I made 101 contacts, including two in Alaska, and two in Canada. You must admit, this is very impressive!

Walt charges $45 for his antenna + shipping.  This is the best 50 bucks I ever spent. Thank you Walt!
