Review Summary For : Amratek Products
Reviews: 1MSRP: $290.00 for complete package.
Description:
A portable 6 through 80m antenna system. Easy to deploy and take down The EZ-Stinger aluminum antenna element is 51 inches long when collapsed, and 17.4 feet long when fully extended. This range covers all bands from 6M thru 20M. With the addition of the EZ Slider 80M loading/matching coil, the 80M band can be covered. With the addition of the EZ Slider 40/30M loading/matching coil, the 40M and the 30M bands can be covered. The EZ Slider loading/matching coils are copper coils. An outside slider on the coil makes tuning easy. The EZ-Tripod antenna base can be ordered with different leg lengths. Each leg is attached separately, so a shorter leg can be added on one side to deploy the tripod on sloping ground. A hole is provided at each end of the legs to allow them to be easily staked to the ground with the included stakes. Stainless steel hub of the tripod has attachment points for clip leads for radials or to attach to a ground plane screen. Tripod breaks down into an easily transportable size. All components can be purchased separately, or as a package.

So far I’ve made 14 POTA activations from 14 different parks in some very inhospitable and barren places throughout Wyoming with the Amratek Products antenna system. It has worked flawlessly, and is much lighter and faster to set up and tune than my previous antenna, a vertical wire on fiberglass pole held up by a large tripod guyed to the ground.

Here are my thoughts and experience on the Amratek Products antenna system:

The lightweight aluminum antenna (EZ-Stinger) is easy to deploy and tune (I didn’t want a stainless steel telescoping antenna because they are probably more lossy, so I was happy to find the Amratek aluminum telescoping antenna). I put the EZ-Stinger antenna in a 2" PVC pipe with caps for protection when transporting it in the SUV.

The tripod deploys and breaks down easily. The ends of the tripod legs have holes to accept the included stakes for secure anchoring to the ground. The tripod hub accepts different leg lengths that allows for deploying the antenna vertically on sloped ground by using one shorter leg than the other two, which I do all the time.

The tripod hub has tabs that make it easy for me to directly clamp ground-plane screens to (it also has holes that accept clip leads and radials, but I just attach the corners of two screens directly to the hub using clamps from The Home Depot).

The low loss copper loading/matching coils for 30/40m and 80m are really easy to tune with the sliders. Mental note to me: When adjusting the coils, also remember to make some adjustments on the antenna element, too. That helps get a lower SWR.

Being a ham, I can't leave well enough alone. Instead of using the included tripod retention pins on a ring to attach the legs to the hub, I use #8 X 1-1/4" Pan Head Phillips sheet metal screws. The threads provide just enough grip to keep the screws in place, which is nice because I keep the tripod assembled when transporting it between parks. But the screws can be wiggled out by hand because the screws are smaller than the holes in the tripod hub and legs, so I can easily remove the legs from the tripod hub to break it down. I carry extra screws for when I inevitably lose them.

The ground stakes at the ends of the tripod legs is a clever design to anchor the tripod. But I wanted more support for the antenna for my own peace-of-mind when the Wyoming winds kick up. I installed a PVC 1-1/4 in. x 1 in. PVC reducer bushing (that has a lip) at the top of the very bottom section of the EZ-Stinger antenna element (another reason why I didn't want one of those short, stainless steel telescoping antenna elements). The bushing sits about five feet above the ground, a perfect height, and is oriented with the lip down, not up. I used a hose clamp right below the bushing to keep it from sliding down. I attached three parachute cord guys around the bushing using slip knots. This allows the antenna element to spin when threading it into the tripod hub without wrapping the guys around the element. The guying is a Wyoming thing, and not something I would expect from the manufacturer. How many hams POTA in 65 MPH winds?

I really, really like the Amratek Products antenna design. The design is very clever and well thought out, and fits exactly what I need. It has made my activation deployments and changing bands easy. I'm grateful for the product, and I wish the company the best of luck. I look forward to other products that they may introduce.
