An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground ...
EFHW-8010-1K-Plus™ Multi-Band End Fed Half Wave Antenna. This is an End-Fed Half-Wave (EFHW*) antenna for 80/40/30/20/17/15/12 and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.

• Hustler 5-BTV 5-band (80-40-20-15-10) ($280, see reviews and its radials and manual and DXE) terminals / 25 ft / 1000 W / 0.0 dBd / 70 mph (0.0 dBd gain without radials; alleged 20 dBd gain with symmetric radials)
I came across the following antenna which covers the 80-10m bands with no traps and just one loading coil. It is called the EFHW-8010 . It is simply a half wave end-fed on 80m which will resonate on all multiples of that frequency, loaded with a small inductance near the feed end.
