Question: What items are included with this preamp?
Document: The product appeared to be inoperative on installation. There was no change in the signal strength of any received channel after installing in accordance with the included instructions. Sent to Audiovox for warranty repair or replacement. We will see what comes back.
My only advice is to know what you're doing before you order. This works very well, but some stations work better without it. That's the nature of this kind of advice. I also recommend not using the water plug that is included, but wrapping waterproof tape around the coax end. The water plug included has a tendency to retain water rather than blocking it, and if water gets in your coax line, it can and will drain all the way down in to your equipment.
I was sick and tired of paying Comcast the monthly bill for only a select few channels we watch and when I called to see what the most basic stripped down cable cost i could get that included locals, it was still nearly $40. So, I purchased an antenna that I currently have in my attic (no real mast installation just yet, just leaning on rafters) and could get 33 channels. But not all of the locals.
The only problem that I encountered was the bracket (U-Bolt) included in the kit for attaching this TV antenna pre-amp to my small dia. mast was the U-Bolt was made for I think 3-inch dia. pipe. I have to climb back to the roof to beef-up the space by inserting a short piece of 1/2-inch dia. PVC garden pipe to finish the job.
I put this up on my antenna mast and was impressed with the construction. It's a cheap little amp that is very well constructed, and the addition of the cable boots was a nice touch. I just wish they had included a sealed cover for the unused coax port, as I only used one of the two available inputs. But I used the third cable boot and just sealed the bottom with some silicone, and it's worked well so far.After installation, performance is OK.
Worked reasonably well for about a month. Died the day after return date, no kidding.Tested amp for gain got zero. I am amazed that the product had only a thirty day warranty. Refurbished items I buy have ninety days or moreClearly .a deficient offering. Do not buy
It did not work at all. I received no signal with the preamp installed. Luckily my signal is strong enough with it.
In addition, it now pulls in new channel that I didn't have previously. So the preamp works but do check the switches.
Same occasional cutouts, but it tells me the problem is probably with the preamp.Too bad, I had high hopes for this amp.
Works as described. Be careful when tightening coaxial connections as over tightening may damage internal connections. I would recommend this preamp.
Answer: The Preamp, Power Insertion Device, some zip-ties, some RG6 boots, and a manual.
