Provides better AM reception, but worse FM reception. You will need 2 antennas.:

I have tested 3 antennas for receiving AM radio in HD, the included loop antenna, the very expensive C-Crane Selectatenna, and the Terk HDR-I.
While the C-Crane antenna provided the best reception, you will need to fuss with it a ton, including positioning and tuning of its dials. For the high price it requires just too much fussing around with for the slight gain in reception.
The Terk antenna performed slightly better than the included loop antenna and slightly worse than the Selectatenna, but... more info

Inadequate for fringe reception:

I bought this to use with my Radio Shack HD Radio unit because I have reception issues where I live. Unfortunately it worked no better for me than the simple antenna supplied with the radio. Believe it or not I had much better luck with an old-fashioned "rabbit ears" TV antenna which was one-third the price. Don't know if it would work in a better location but it didn't help me.

Not the best reception or cost. Try Philips.:

My HD radio is a Sony XDR-S3HD. So this comparison is only true for this radio and my location (just north of Washington DC). I tried the accompanying wire and dipole antennas first, and then tried this Terk HDRI Antenna and a Philips Magnavox MANT-110 Indoor Passive Antenna. The Terk box says it is specifically for HD radio. The Philips box says it is for VHF/UHF/FM/HDTV.
The dipole worked best overall of the two included with the Sony but I experienced a number of drops when there was movement,... more info

Absolutely no improvement whatsoever, only disadvantages:

This unit, at its max. gain setting, pulls in ZERO additional HD channels. Existing ones are not improved either. It's totally useless. To make things worse, it requires AC power, but for what? To lit the white LED light in front for show? Seriously, it draws electricity for WHAT purpose if it doesn't improve reception ONE SINGLE BIT? Avoid at all cost.
