HF and 6m-band portable transceiver: Lab599 Discovery TX-500 with external 2Ah (~25Wh) and 4Ah (~50Wh) LiFePo4 battery packs, max. 10W RF output power.
HF, VHF and UHF portable transceiver: FT-818ND with internal 3Ah (~30Wh) LiPo and external 3S 18650 Li-Ion battery holder (~30Wh), max. 6W RF output power.
When travelling by plane, I swap the three 18650 cells into an empty USB power bank, which allows to charge them ;-).
VHF and UHF handheld transceiver: FT-2DE, also used for APRS2SOTA and APRS, max. 5W RF output power.
Commercial and home-made multi-band resonant half-wave end-fed dipoles for the 10-, 15-, 17-, 20-, 30-, 40- and 60-meter bands. Please see my corresponding document: A Portable 7-Band End-Fed Half-Wave (EFHW) Antenna (version 1.1).
With an additional loading coil and some length of wire, the 80- and 160-meter band can be used as well, albeit with less efficiency.
Typically, I strive for an inverted-L configuration, supported by a 6m-tall telescopic glass fiber mast (image).
