my mom used to tell the story of the lights going out in the house and found me with a fork in my hand and a black mark on the outlet.
we sold the house and the mark was still there.

Ya gotta learn somehow. Like I used to hear, "Never trust a skinny cook.". In this case, never trust an electrician/technician that hasn't been lit up a few times. Anyone that hasn't been isn't trying hard enough.

that is why i used to tell my kids to use a fork !
many people get hurt with the knife and there is little information on forks and doing that.
so that proves it is safer.
my 'kids' are in their 30's now and understand my humor.

Found the manual online.

The antenna has two cables coming out of it. One is a coaxial cable for connection to the TV. The other is a USB cord, for powering the amplifier.


Try the antenna with the USB cord unplugged first and see if it does what you need. If not, try powering it up. Not going to damage the scanner, just like it wouldn't damage the TV set.
Awesome! Thank you for looking at that information.

There ya go! My oldest is 19 going on 40 and if I could get him to just stick the darn fork or butteknife in a toaster I would be somewhat happy. He was almost killed in a car wreck a year and a half ago, getting in a car with a friend who was drunk and hit a tree at 90 mph after passing out.

I wish he would just stick to minor jolts from a toaster 🤣

Hello all,

Just thought I would provide an update now that I have received the Inland AN-5008 HDTV antenna and got it up and running.

When I first tested it without powering up, there was very little signal to my local site, and no signal to my 2nd site (neighboring site that has the bulk of my listening approx 18 miles southwest and behind a mesa with no line of site possible).

After powering it up, the signal returned to both sites showing full bars. Once I turned the Analyze function on for the sites, I am getting great signal and signal quality on both sites! 👌

So far, this thing is working amazingly for me, especially for that neighboring site that's been an absolute mess to get good signal from. I'm quite impressed! And I've only stood it up in the window as a test, I'm sure it can be placed better, and maybe a little better results.

I would have never imagined such a cheap HDTV antenna would work this great. What a mindblower...

Good to know..I just might try one. Thanks!

Absolutely glad to help.

I went ahead and mounted it onto a vent pipe outdoors on the roof after I wrote my initial thoughts.

Seems like having it outdoors vs. Inside in the window maybe isn't much difference. Turned it in several directions to find that sweet spot. I took my pesky neighboring site from about a 20-25% signal strength to what seems like 75-80% (based on the Analyze graph on the SDS200).

This thing is really rocking, and doing amazing now! I would highly recommend trying one for the low cost.

There are no TV stations or translators between 108-174 MHz or above 698 MHz.
Well, I beg to differ with you. I get channel 8 simulcast via translator on 34 plus others.
Translators operate on any UHF terrestrial channel pending location.

Over-the-air. Cable TV uses the frequencies 108-174MHz for TV channels.
Our local cable supplies all 68 channels. It's digital with 6 MHz per chammel, and a gap at 88 to 108 MHz. there is a guard band between channels.
Subscribers get 62 channels, where like hotels get additional content like porn channels.

I know cable uses whatever they can to maximize use of their bandwidth. No TV channels should be broadcasting OTA in the aircraft band. When it comes to UHF, there certainly can still be a few outliers out there. BUT, UHF OTA channels 52 to 69 were de-allocated for TV and became the 700MHz band, and more recently channels 38 to 51 were de-allocated and became the 600MHz band. That leaves OTA channels 2 to 36 for TV (as 37 has other uses).

And how about a 3000 mile antenna⁉️😵‍💫 there is a $7 coupon👎

Hey all.. got a question.

Been using the HDTV antenna for a little while. Been going very well. BUT... I ran into a snag.

Turns out the antenna can not be outdoors, although the directions clearly state a mounting option for outdoors. This due to rain and its ability to only be exposed to very light splashes and very light water exposure.

That said, brought it back inside and found a good spot. I am able to pick up both of my sites ( 1 east of me, 1 south west) by pointing it directly south. Analyze function shows great signal strength and quality.

Noticed today it seems to possibly be missing some on the site east of me. Possibly due to not having it pointed more that way? Not sure since the signal strength shows almost full. This could also be a fluke, and I will need to watch it.

Here's my question, although it may be a dumb one. If I'm needing the antenna pointed more in the direction of the specific site, is it possible to just buy a antenna splitter, and another antenna and point 1 antenna at the east site, and 1 at the southwest site? Not sure how that works, but have seen it mentioned with using 2 yagis, although it appeared you may lose a little signal from each antenna?

Anyways, any advice on this would be greatly appreciated, in case I would need to do something different to get better results.

Thanks!

Connecting two antennas together requires phasing harnesses and that gets to be problematic if you want it to work on more than one little slice of the band. Phasing harness length is critical and requires calculating the frequency and the velocity of propagation factor of the coax. Not easy to do.
Simply Teeing them together can result in worse signal.

Thanks for that clarification.

I'm not sure what or why I'm having the issue, I just know it appears I'm only hearing some of the radio transmissions from the 1 talkgroup. Thought maybe a signal issue, but as I said the signal strength and quality are both high on the Analyze function and my RSSI values are in the -66 to -70. I will need to see what I can find as I'm hearing a fair amount from that TG.

Anyways, thanks for that advice on that. Much appreciated!
