    It is described as "Active" and containing an amplifier but I don't see a power cord. Is this active (110V powered) or passive (no signal boost, just a coax connection between antenna and TV)?
    A shopper on Dec 23, 2016
    BEST ANSWER: It is indeed active. It's not pictured, but the HD3 I received today came with a wall outlet powered power supply with a cord that plugs into the rectangular amp that is inline with the antenna's coax cable in the picture.
    Does this antenna work with FM radio?
    A shopper on Dec 23, 2016
    BEST ANSWER: Yes. Works well too. Mine is hooked up in my basement where normal antennae wasn't working and now get all local channels
    How long is the cord?
    Jared K on Dec 23, 2016
    BEST ANSWER: Antenna coax and the power adapter's cord are each approximately 5 feet long.
    Which RF frequencies does the antenna cover? Only UHF RF 14-69? Or does it also cover VHF-High RF 7-13?
    A shopper on Dec 24, 2016
    BEST ANSWER: It would be nice if Monoprice posted the specs. The instruction card that came with the antenna lists specifications as VHF 174MHz - 230MHz and UHF 470MHz - 862MHz. According to Wikipedia as of tonight, this range is RF 7-13 and UHF 14-69.
    how wide is this antenna?
    A shopper on Dec 9, 2016
    BEST ANSWER: The antenna is 2.25" x 15".
    How do you mount or setup the antenna?
    A shopper on Jan 17, 2017
    BEST ANSWER: We mounted this on a blind, where the bottom piece fit in between the slots. You could set this on top of the TV or it could be mounted to a wall, but to use the power transformer it must be close to an outlet. It works great!!
    Is this an indoor only antenna? And can a longer cable be attached to it?
    A shopper on Sep 1, 2017
    BEST ANSWER: I only use this antenna indoor. It does not look like it is designed for outdoor use. Besides, you need to continue it to power to get the maximum range.

    Works good, but only close in the ergo field .
    The antanea works good. The cabling is designed somewhat backwards. The last bit of cable from the power converter to the antanea is only about 8". So you have to drag the power cable and the antanea cable up to where you mount the antanea ! So you end up with a power strip up in the air so you can plug in your antanea!

    Failed at detection of channels, reception
    While this may work for some it didn't for me. After re-scanning with this antennae fewer channels were detected than with my old rabbit ears I was hoping to replace. Of the channels it did detect the reception was worse than the rabbit ears with freezes and lose of signal on some channels. Being located in a major metro area there are at least 50 available digital broadcast channels within 30 miles but this antennae failed to detect half of them. Went back to using the rabbit ears.

    Great reception
    Greatly improved our reception in the basement family room.
    The downside is, the power plug in is too high. It is a little difficult to hide the wires.

    hdtv antenna
    It does not have the power I expected. It was very reasonable though; I would say it has a 20 mi. range.

    Not the greatest reception. Even without an amplifier, my other 25 mile range antenna gets better reception than this. It will work, but bit disappointed by performance.

    Gave these as Mothers day gifts
    I order 2 of these Slim Active HD3 HDTV Antennas with 40 Mile Ranges. I gave them to both of my daughters for a Mothers Day Gift. They had both tried to cut the "so called cable", with no luck. When they had both bought HDTV inside antennas at the local store, they had problems getting even the local channels, that were within 25 miles. I saw these in my email from Monoprice for half of the price that they both had payed locally. "Dad To the Rescue"! Now they both have 14 and 15 channels opposed to 3 and 4 respectively! Thanks again Monoprice. The perfect gift.

    Picks up everything
    Have this installed about 12 miles east of the Indianapolis antenna farm on the north side of town. We can pick up all of the standard channels in HD without nary a problem. It's nice and sleek and fits right in above the Monoprice wall mount holding up the TV.

    Great price on this antenna!
    Just "cut the cable", but didn't want to lose my PBS and local stations here in the Bay Area. Added these Slim Active HD3 Antennae to each TV and voila! Great reception in an area near the Bay where connectivity is volatile. Thanks to Monoprice for such a great deal- the price is right!

    Works Great!
    Was going to hook up on the TV in my shop but ended up installing on my stereo in my basement where I wasn't getting any FM channels. Works like a charm, and get all station I get in my car. Will be getting a second for my shop. Thanks Monoprice!
