 Just what I needed!Jun 23, 2011
By BlueJupiter
I got this amp to try and increase my signal strength for ABC. I can get ABC very rarely and even when I do, it fades quickly. Once this amp was installed and plugged in, I not only had consistent ABC, but I picked up more channels! I have the Antennas Direct ClearStream4 antenna mounted on the J pole. This amp was a breeze to install on the J mount pole, but probably because all of the components are Antennas Direct. This has been the best investment thus far for my over-the-air channels.

 Make sure you need thisApr 11, 2011
By Johnny V
When I installed this item, the power supply inverter got real hot and melted. I was told by a tech that this was due to a faulty cable to the antenna. I had to pay return shipping to have a replacement sent. I am approx 50 and 60 miles from the broadcast towers I was trying to hit. I was hoping this would strengthen my signal and eliminate some scrambling from the farthest sights.
Once I hooked up the new booster, I lost about half my channel signals. I am not sure why so be sure to do your homework before you drop $100 on this. I did buy brand new coax to the antenna and this greatly helped my reception WITHOUT the booster. Now I have something I apparently do not need and am out $100, but hey, that is still only 2-3 months cable bill. No worries.
Like I said, I probably bought the wrong item for my application. Be sure you understand what it is you need before you buy.
Good luck!

Excellent preampMar 10, 2012
By Mark Munkacsy
I've used three different antenna/amp arrangements so far to try and pick up distant (55 mile) stations. I first tried using an amplified indoor antenna (GE TV24769) mounted up in my attic. Local reception (~25 miles) was very good, distant stations were generally unwatchable. I replaced that antenna with a Channel Master Model 2018 directional antenna with a Motorola distribution amplifier about 10 feet downstream from the antenna. Distant station reception improved, but was marginal, particularly in rain and snow. Local reception was pretty good, but I lost one of the local stations that was off to the side of the antenna pattern. Then I added this Antennas Direct CPA19 preamp, and things became really, really good. I chose this preamp because of its good noise figure. I'm now using both the Antennas Direct preamp and also the Motorola distribution amp. The combination works well for both local and for distant stations. Overload is not a problem except for FM stations. The CPA19 preamp is mounted right on the antenna mast.
I now get crystal-clear reception of every station within that 55 mile radius. I couldn't be happier.
Works as expected - great pre-ampMay 12, 2012
By Clarke H. Morledge
When the TV industry switched from analog to digital over the air a few years ago, my antenna was longer able to pick up the new digital stations in my rural area. I bought the CPA19 with the hope that it would remedy the situation. It did exactly that. Just recently, I had to replace my CPA19 due to a lightning strike that knocked out the preamp. The unit works perfectly. The only reason I gave it 4 stars is that on the original unit, the 12volt AC-to-DC adapter was dead. But the folks at Antennas Direct replaced my adapter within a few days, no questions asked. Great product. Great customer service.
seems to be a very good RF amplifierApr 18, 2012
By S. Nelson
I bought this CPA19 RF pre-amplifier last weekend, and it has worked very well. I am 66 miles south of the Walnut Grove, California broadcast antenna farm. This amplifier, combined with the HD Stacker antenna, works very well for receiving signals from there. Even PBS (KVIE 6.1; RF Ch9) and ABC (KXTV 10.1; RF Ch10) which broadcast at lower powers come in with a strong signal (5 out of 7 bars on my HDTV receiver signal strength meter) and so far there has been no pixel breakup as there was with my previous antenna+preamp.
My antenna is bolted to the chimney (with a chimney brace) about 12 feet above the top of the chimney. We rarely use the chimney, so this should be OK. This puts the antenna about 35 feed above the ground. Ordinarily, I should have installed the CPA19 pre-amp right at the antenna, but for serviceability reasons, I have the CPA19 in the attic where the 30-foot RG6 cable comes in from the antenna.
I didn't have any problems installing the CPA19, and I unscrewed the large plastic "pole piece" so that just the metal pre-amp unit itself was used.
The unit is warm to the touch, so I'm unclear if the metal mast pole was intended to be used as a heat-sink or not. In my case, summer outdoor air temperatures peak at 118 degrees, so a metal pole would be hotter than this. But I have it in the attic screwed to a framing 2x4 (no heat conduction) near a gable vent. Time will tell if this is a problem or not.
The CPA19 claims to be a low noise amplifier, and I certainly get more stations than I used to with my ChannelMaster 7777 pre-amp that I used to have. But some of this is also due to the HD Stacker antenna that I also switched to at the same time (from a 23 year old Winegard antenna that was falling apart). I am also able to get a few Fresno stations (95 miles away) which is even in the wrong direction (off main-beam) for my antenna (I don't have a rotator), so I highly recommend the CPA19.
Note that the CPA19 power supply injector that comes with the unit has a captive dual-wire power feed from the transformer (i.e. don't try to unscrew the type-F connector like I did to try to undo the power feed).

Edit: according to AD Tech, the CPA19 is indeed intended to use the pole as a heat sink. But since mine is in the attic, there is no pole. So I bought an aluminum heat sink from Amazon (http://www.amazon.com/gp/product/B005D6145G), some thermal conductive goop, and will use self taping screws to mount the CPA19's metal housing to this aluminum heat sink.
I also increased my rating to 5 stars based on their excellent customer service.
