Correction: some FM broadcast transmit antennas have an input VSWR less than
1.15:1 from 88 to 108 MHz (50 ohm coaxial environment).

I don't think a correction is necessary, comparing apples and oranges.

It depends on the application as to what VSWR bandwidth is necessary, but
certainly it is not difficult or expensive in many antenna designs to span
several hundred kilohertz with a good match to the transmission line.
A 100mhz antenna has several hundred khz bandwidth using #8 wire, but try a
dipole on 1.8 mhz using #8 and you have 10-20 khz.
You are apparently an expert on VHF antennas. I am an Amateur. The antennas
discussed on this group are often 1.8-30 MHZ. HF and VHF antennas are just
alike, but they are different. Got any idea about 1.8 mhz bandwidth?
