HF UHF HOA Buster Antenna

HF UHF Base antenna

The HOA Buster uses your largest antenna, which are your gutters, that is already installed to operate on 10 to 80 Meters and 440 & 900 MHz and are *built to order based upon your color section.

VHF HF Portable EmComm antenna

Take it with you! Perfect for portable or EmComm deployments when you’re away from home using the optional 2-80M 60′ EmComm Element is deployed. Just remove the ground stake from the mount. Then attach the mount to any mast, tree, etc. Feel free to still run a ground wire to the ‘ground’ bolt on your rig to the metal stake at your operating position.

Specifications 

Frequency: 10M to 80M (29.7MHz to 3.5MHz) + 440 & 900 MHz
Max Power (Watts): 250 PEP SSB, 125 CW, or 25 watts for digital modes.
RF Connection: SO-239

Included

• 1 HOA Matching network,
• 1 Spike Mount, and
• 1 Eight-foot jumper wire;
  • The jumper wire can be made shorter or longer upon request. Just enter a note in the Comment field when you CHECK OUT for the length you want.
    • 8 feet is the optimum length to not degrade performance.
    • 12 feet is the maximum length to keep the wire from touching the ground.
    • 5 feet is the length to keep performance at an acceptable level.
    • 18 inches is the minimum length to function with degraded performance.

Analysis

Deployment

1. Push the included Mounting Spike into the ground,
2. Install the included jumper wire by fully extending it between the HOA Buster Match and downspout, so that it does not touch the ground. Then simply use the included clip at the end of the jumper wire to secure it into place,
3. Then attach any length of coax to the connector on the bottom of the AutoMatch and run your coax to your equipment.

More Information

Never Loosen any of the Bolts, Washers, Nuts, or Caps on the HOA Buster’s match. Otherwise, you’ll need an impact wrench to tighten them. 

Operationally, the HOA Buster is a matching network that uses gutters as the antenna element for 10-80 Meters + 440 & 900 MHz frequencies. The matching network then has a metal Mounting Spike under it, which is used to complete the circuit and provide a static drain. Please note that this system is built to order in a PVC Housing that is customizable in many colors so please be patient with us after you place your order.

This is a permanent outdoor system that weathers well.

There’s no maximum size for the gutter that can be used, and a minimum combined length of the gutter and downspouts should be at least 25 feet. Make sure that your gutter, downspout, or flashing isn’t grounded or touching the ground. Then just feed the gutter from one end as if it were an end-fed antenna.

There are no feed-line minimums/maximums.

What detracts from gutters performing well as an antenna, are often if it is either steel/aluminum or stucco siding/roof. Whether your siding is stucco, there may be chicken wire under it. There may also be Mesh Fiberglass Stucco Netting, which has no negative impact. So, check for that to ensure that metallic wire does not exist under your stucco siding, which is present will have an absorption rate for the RF that makes it difficult to either receive or transmit. Again, this is also true whether your siding or roof is aluminum or if the insulation under your siding/roof has aluminum/foil under it.

The 440 MHz and 900MHz band is a part of the UHF (Ultra High Frequency) radio spectrum. The most common polarization used in this band is vertical polarization. However, gutters are polarized horizontally. This horizontal or vertical polarization of the antenna is the orientation of the electric field generated by the antenna. The polarization of the transmitting and receiving antennas must match for efficient communication. You will then experience far less performance when communicating between vertically and horizontally polarized antennas vs two antennas are similarly polarized.

Options

An optional 60-foot EmComm element activates 2 through 80 Meters and is used instead of a gutter. This is very useful if you are deployed on a beach, mountain, or in a park. MORE INFORMATION

The optional padded 600D field bag will hold all of the antenna’s components and more!
