Add antenna quick reference guides to all mode sidebar panels
Each SDR mode now includes frequency-specific antenna guidance: - Pager: VHF/UHF dipole info for 153/929 MHz bands - 433 MHz Sensors: quarter-wave ground plane for ISM band - Utility Meters: 912 MHz stock antenna tips and upgrades - APRS: 2m band dipole and commercial options for 144.39 MHz - SSTV: V-dipole for ISS reception at 145.800 MHz - AIS: marine VHF antenna for 162 MHz vessel tracking - Listening Post: wideband discone recommendation with band table - Meshtastic: LoRa 915/868 MHz antenna upgrades and placement - ADS-B: 1090 MHz collinear, commercial options, LNA/placement Each guide includes antenna type, element lengths, placement tips, and a quick reference table with key specs for the mode. https://claude.ai/code/session_01FjLTkyELaqh27U1wEXngFQ
