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, including 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.

Open Field Antenna Mast Mount

In two previous blog posts (Drive-onTrailer-Hitch), I shared my heavy duty drive-on, and trailer-hitch antenna mast mount creations. In this post, I want to share a third option, my “Open-Field” mast mount.

There are times when you need to put up a tall antenna mast away from a vehicle. This may be in a park for a POTA activation, or in a remote field as an EMCOMM operator.

Many Hams will stand up a tall antenna mast using long guy wires, connected about 1/2 way up the mast. This setup usually requires two people to put in place. Deploying high/long guy wires is cumbersome, and takes up a lot of space. In most cases, it is not necessary.

Trailer Hitch Antenna Mast Mount

My heavy duty, “Drive-On”, mast mount is universal. It can be used with any type of vehicle. Those of you that own a vehicle with a trailer hitch, maybe interested in my hack of a trailer hitch flag-pole mount.

I ordered a trailer hitch flag-pole mount from Amazon. These devices are designed to hold a flag-pole. This particular unit has a 2.3″ diameter. I had  a requirement that the size of the pipe had to be larger that 2.25″, due to the large rubber caps on my TN07 telescoping mast.

Without an insert, the flag-pole mount pipe is too large for both my TN07 and DX Commander masts. I discovered a 2″ PVC pipe fits into the flag-pole mount perfectly. The outside diameter of the pipe is 2.3″ (@60 mm). The inside diameter is 2″ (@50 mm).

I cut a length of the 2″ PVC pipe to 36″.  I painted it with Rustoleum paint from a rattle can.
