These antennas are especially-made for NOAA weather satellite reception and are tuned to 137MHz to receive polar orbiting satellite signals. This is part of Project TIROS for element14 presents.

Thanks to "Tinker John" (W5CYF) for this useful antenna accessory. For around $25 and a few locally available materials, you can make a sturdy tilt mast base for your vertical antenna. The homebrewed device will come in handy should a storm arise or nosey neighbors ask questions about that pole sticking up in your backyard. I've used a similar tilt over arrangement for my 80 meter vertical helix.  Out of sight out of mind.  Plus, the tilt over base reduces the chance of wind damage or lightning striking your vertical antenna. Here are some of John's comments: Using off the shelf material and hardware you can build a simple tilt base for your vertical antenna. EZ Project using hand tools and less than $25 in material.
