Amazing GOOP for Ham Radio

You have probably seen Amazing GOOP® in your local hardware store. This product with the funny-sounding name has been around for decades. I’ve been using it for ham radio applications for the past 25 years or so.

I recently did some extensive research on Amazing GOOP. (Full disclosure: OK. I lied. My “extensive research” merely consisted of a quick Google search and reading a Wikipedia article.) Back in 1972, a senior executive in the aerospace industry created a product called “Shoe GOO®.” Shoe GOO was intended to repair rubber-soled shoes. In fact, I first used it many years ago to repair a pair of rubber fishing waders. The original Shoe GOO is still produced by Eclectic Products. They also produce a wide variety of waterproof, flexible adhesives for a host of applications and environments. The Amazing GOOP® product line is what I’ve been using for ham radio applications.

Here are some of the uses I’ve found for it:

Sealing portable antenna connections. This was my original use for Amazing GOOP. After soldering the connections between the feedline and dipole elements, I seal them up with Amazing GOOP. I’ve never had any corrosion problems like you can run into with RTV.

This is the center connector of the doublet that I use for my "Up and Outer" antenna. I used Amazing GOOP to seal the soldered connections and help anchor the wires in place. This particular antenna was built about 15 years ago and is still holding up well.

Wire end loops. Instead of end insulators for my portable wire antennas, I just form small loops. I twist the wire to form a loop and use Amazing GOOP to hold the wire twists in place. (This works very well for my lightweight portable wire antennas but I would use end insulators for permanent antennas.)

End loop on one of my (many) wire antennas for portable use. I attach my throwing line directly to the loop, foregoing an insulator. With smaller diameter wire, I sometimes put some shrink wrap over the GOOP.

Powerpole® connectors. I’m a “belt and suspenders” kind of guy. So, I crimp and solder my Powerpole connectors. After I assemble and test them, I apply some Amazing GOOP where the wires enter the connector housing. This provides strain relief and makes them very rugged. I also place a dab of GOOP on both ends of the roll pin. This keeps them from popping out in the field.

Miniature audio connectors. I’m hard on the little 1/8″ audio plugs I use on my CW keys. So, after soldering and testing them, I put some GOOP on the connections before screwing on the plastic housing. Then, I put some GOOP on the wires where they enter the connector to add strain relief. I also apply GOOP to spade/ring lugs after they are crimped and soldered.

A 3.5mm plug and Anderson Powerpole connector after I have applied GOOP as a strain relief. Sure, they look a bit ugly but these connectors are pretty much bomb-proof. These items have seen heavy use in the field over the past 3 or 4 years.

My CW Clipboard. I used GOOP to attach the steel washers to the clipboards I use in the field. The washers are how I attach the magnetic bases of my portable paddles and straight key to the clipboard.

My rainspout antenna. I use a liberal amount of GOOP to seal the connection to my trusty rainspout antenna. GOOP holds up well to the continuous exposure to the elements.

Hopefully, the pictures will clarify my descriptions.

If I can find it, I use one of the GOOP varieties intended for outdoor use for my rainspout and portable wire antennas. Right now, I’m using Amazing GOOP Max. Regular old household variety of Amazing GOOP is fine for most uses, though. For all applications, I like to let the GOOP cure overnight before use.

A few disclaimers are in order:

  • This stuff is permanent. Be sure whatever you’re using it on works before sealing it up with GOOP.
  • This stuff works for me, as described. I don’t know what you’re using it for or how you’re using it, so your results may vary.
  • I have absolutely no financial interests in this product. I’m just a satisfied consumer.

So, that’s it. I hope you found it useful.
