Start with the rules

Before you hide anything, find out what actually applies to you. Condo and strata bylaws, rental agreements and some neighbourhood covenants can restrict outdoor antennas. In Canada, Innovation, Science and Economic Development (ISED) sets the rules for antenna structures, and most small amateur antennas don’t need any public consultation. Knowing your situation lets you choose the right approach instead of guessing.

Whatever you build, it must still meet Safety Code 6 for RF exposure. That matters more with hidden antennas, because they tend to be closer to people.

Outdoor antennas that blend in

• Thin wire: dark, thin insulated wire, 18 to 26 gauge, is nearly invisible against trees, rooflines and the sky. An end-fed or random wire running to a back fence often goes unnoticed for years.
• Flagpole vertical: a flagpole with a vertical inside or the pole itself as the radiator. Nobody looks twice at a flag.
• Under the eaves or along the fence: wire along the gutter line or the top of a fence works better than you’d expect on the higher bands.
• Rain gutter or downspout: metal gutters can be tuned as an antenna with an automatic tuner at the base. Results vary, but some people do very well.

Indoor and attic antennas

• Attic dipole: a wire dipole stapled to the rafters. Keep it away from wiring and ductwork where you can, and expect some noise pickup.
• Magnetic loop: a small loop by a window or on a balcony is probably the best indoor HF antenna. It’s quiet and works on several bands, but it needs retuning on every frequency change.
• Balcony vertical: a short whip on a clamp mount, with a counterpoise along the railing.
• VHF/UHF: a small vertical in the attic or near an upstairs window will often reach a local repeater, especially one as well placed as the VE6DOK repeater.

Operating with a compromise antenna

• Use digital modes: FT8 and other weak-signal modes make up for a lot of antenna shortcomings.
• Keep power modest indoors: lower power reduces RF exposure, interference with household electronics, and complaints.
• Choke the feedline: a common-mode choke at the feed point keeps RF off the coax and out of the house.
• Fight the noise: switching power supplies, chargers and LED lights are the usual culprits. Turning off breakers one at a time will find most of them.

Being a good neighbour

The best stealth antenna is one nobody has a reason to look for. If your signal never shows up on a neighbour’s TV, phone or doorbell, they’re very unlikely to go searching for the cause.
