Joe Cro N3IBX says his "big antenna" is resonant from 1500 kHz to 46
mHz.

He's defining "resonant" as no reflections. Instead of a
standing-wave antenna, he is sacrificing half his power
(or more) in the resistors to avoid reflections and turning
the antenna into a traveling-wave antenna.

It is a military inverted-V, 110 ft. long total, with each end
terminated in a 150 ohm resistor driven into the ground, center fed
through a 9:1 balun.

Assuming this is not an April 1 joke:

It's somewhat like a terminated-V antenna, described in the
ARRL Antenna Book.

(1) What are the drawbacks to this antenna?

He is losing at least half his power in the resistors.
Wouldn't you rather radiate that power? I go to great
lengths to obtain an extra 1 dB.

(2) What is the feedline?

With a 9:1 balun, it can be coax since there are so few
reflections.
