Baluns on Log Periodic Antennas - Some antenna manufacturers place baluns at the incorrect location in LPDA arrays, or tell you to route the cable incorrectly. This can cause substantial RFI and all sorts of weird problems like RF into house wiring.

VSWR Reactive Power - Many antennas and antenna designers neglect the true cause of loss. The major problem using short antennas is the reactance, not the length

Tuning HF Coaxial Antenna Traps - The problem with making your own trapped HF antennas is usually getting the coaxial traps tuned to frequency.

Coffee Can WiFi Antenna - This wi-fi antenna design is a much simpler DIY project than the pringles cantenna. Basically there are 3 parts to a build-your-own 2.4 Ghz cantenna kit: a pigtail, an N-female connector and a metal coffee can.

Pringles WiFi Antenna - DIY Wifi Antenna with a pringles can and extend your wifi signal, also known as cantenna.
