A Log Periodic!!
~6 dB gain continuously from 13.5 to 33 MHz, F/B from 15 to 45 dB
[frequency dependent], VSWR less than 1.6 to 1 across the full frequency
range continuously, higher efficiency than a Yagi [99.2% versus 88.4%[ 3
element monoband] or [30.9% for small 3 band Yagi], no traps, low wind
loads, eight elements, 18 foot boom, mounts on a Rohn 25, turned easily
with a Yaesu SA 800, ~$600 [when I bought mine], TENNADYNE T8. A T6 is
available with slightly higher maximum VSWR [1.8] and slightly lower
gain.

My antenna!!!
I have NO financial interest in Tennadyne. I'm a 100% satisfied user, a
retired Electrical/Aerospace Engineer and a retired antenna range
manager, who knows that the USAF/FAA/State Dept. use LPs for most long
haul HF.
