Battery Power for the Small-Space Shack: What LiFePO4 Actually Fixes

How a 12V LiFePO4 battery replaces a switching supply in a restricted-space shack: the noise floor it buys, the runtime math, and the charging habit that undoes both.

VHF and UHF From a Restricted Space: Small Antennas, Unforgiving Physics

A 2m antenna fits anywhere and works almost nowhere indoors. Material attenuation, polarization loss, the feedline budget, and what to build instead.

Temporary Beats Permanent: The Mast-and-Tripod Station Most CC&Rs Don't Reach

A freestanding mast and tripod that sets up in minutes and stores in a closet: why non-anchored antenna gear sidesteps a lot of CC&R architectural review, and what to buy.

The Mast That Goes Away: Temporary Verticals on a Deed-Restricted Lot

Stealth by duration instead of by camouflage: what your covenant actually regulates, which telescoping poles survive real wind, and why setup time decides whether this works.

Measuring a Compromise Antenna: What the NanoVNA Shows That an SWR Meter Hides

A low SWR at the shack can mean a lossy feedline rather than a working antenna. What R plus jX tells you, and how to measure it for under $90.

Invisible Wire Antennas: Getting an End-Fed Half-Wave Into an HOA Yard

Visibility is an engineering spec, not a hope. Wire gauge and finish, tree launch technique, where the feed point hides, and what a drive-by inspection actually resolves.
