I have Dish satellite hdtv service and am getting an objectionable hum from my HTS FM radio only. Would this isolator. placed between the HTS FM wire antenna and the FM antenna input on the HTS solve my issue. If not, anything else I can try ?

It worked for me. It kept noise coming in on cable connection from making annoying hum when I had cable box connected to audio car in computer. I think it would be worth a try.

What's humming??? The antenna or the amplifier/rotor box???? Mine doesn't hummm at all.......

i doubt it. from what i know having your equipment plugged into different circuits would only make the hum worse. in any case if your equipment hums it is probably not worth spending this much money to fix the problem. good equipment doesn't hum no matter where you plug it in. i suggest getting equipment that uses balanced ( XLR ) or digital ( Optical / Coaxial / XLR ) interconnects. Regular consumer unbalanced analog technology is inherently inferior and was never designed for high performance.

Buy a static arrestor to go in line w/your coax cable and mount it low to the ground. You can get a ground rod at any home center w/copper wire and associated clamps. Just be aware of what may be underground where you are going to drive in rod. My antenna is mounted about 5 ft above roof and receives excellent HD FM!

I noticed it too. When the device is connected via the instrument connection the floating ground will cancel any noise. One must remember, this isn't a professional piece of equipment with layers and layers of MOSFETS, JFETS AND TRANSISTORS To switch on and of the signal. So, even though there is no signal, it's amplifying the hum from the AC transformer as well. In common terms, it needs to be connected to a device to cancel the noise. Even in the ground, or lift phase.

It's difficult to say. While it could be component failure in the amp, it could also be interference between your location and the broadcaster, such as larger trees than before, newer buildings or even machinery in factories. Digital transmissions are delicate, and I find my reception is affected even by windy days moving the trees and branches a lot. I know how frustrating it is. Try moving the antenna location, even a foot one way or the other can make a huge difference with DTV interference. My internet-cable company installed a new modem in my house and now I can't get any AM radio reception due to the terrible noise it is silently generating on the airwaves. Just loud buzzing. As soon as I unplug it, I get perfect reception all over the house. Could you have anything new, nearby, ie Microwave oven, electronic power supply for laptops or phone chargers etc? I find that a lot of the offshore made electronics lacks proper shielding. Very poorly made stuff. Just some ideas. Good luck.

Hi Kenny. Ground lift can sometimes be used to reduce or eliminate 60Hz hum, caused by ground loops. Ground loop can occur when you have multiple pieces of equipment connected to different power sources. Most of the time you'll want this off (not lifted) unless you are experiencing hum. Coax is for connecting similarly equipped digital equipment (only). It's best used to sync multiple audio interfaces. If you don't know what you need it for, you probably don't. Hope this helps! :) ~ Heather

The hum might be due to a ground loop. This problem often happens when you interconnect devices via RF/audio/video/etc. cable that are plugged into electrical circuits with different grounds. To troubleshoot this, try disconnecting FM antenna, input and/or output cables from your receiver. Assuming that you have any kind of cable connecting the TV to the receiver, also try removing the RF cable from the TV. Cable TV hookups are reputed to be common causes for ground loops. If the hum goes away with a particular cable removed, search online for a ground loop eliminator device for that type of connection. An inexpensive audio ground loop eliminator is available at RadioShack stores; higher-end audio ground loop eliminators are available online. Cable TV ground loop eliminators are available from online sources. For further information, search the Web for the words "ground loop". Hope this helps! Dave

I am no expert, but I don't believe it will compensate for a houses internal RF noise generated by appliances and such. What it can do is magnify the signal in the small range of the station you are tuning in...because you tune the terk antenna in also...the terk's tuner is labeled with the AM frequencies just like the radio is. Now the question is...will the radio have enough 'added' signal to overcome your houses internal RF noise ? Maybe.

As you can see the antenna is a telescoping rod. I took it to a town 10 miles north of the station and had trouble pulling in my HD channel. So it's not so hot when it comes to sensitivity. (Selectivity is marvelous, since it's "all or nothing" with HD radio.)

Sometimes if I turn my head at just the right angle I get the hissing and crackling. It appears to be when I am at an exact 90 degrees. Turning the transmitter to away from 90 degrees helps. Also when the microwave is in use, it makes a lot of noise.

it solved my humming problem when i used 2 or more components plugged into my receiver. but when i got a more powerful amp i didnt need it. i would try it...you can always return it.

Josh, I don't know if you purchased this Monster sub cable or not, but I too had a hum with the manufacturers provided sub cable, and I have high end Paradigm and Denon equipment. I purchased the Monster sub cable and my hum went away.........highly recommended.Cobra

Yes! I get this annoying hum that only goes (mostly) away if the bass control is all the way down. The volume control has no effect and it doesn't matter if the satellite speakers are plugged in or not. I wanted to put this next to my bed but the hum is intolerable. I plan to return it. I don't know if I should try getting a replacement or if I should give up on this model entirely.I got a replacement and it is worse. It buzzes even with the power off. With the power on I can hear the hum across the (quiet) room. When it is close enough to reach the control from my bed, the hum drives me crazy. Yes!

Are you sure it isn't the subwoofer? It stays on all the time even when the system is turned off and produces a low level hum, constantly. That seems to be the norm for all the subs and the Onkyo receivers. I was surprised to walk into my media room and hear the hum coming from the sub and the system was turned off. Sub is always in stand by. Just a thought.

I just recently bought one of these to use with my H24 receiver. The dish comes with a single cable to connect to the receiver, meaning it will operate a single tuner.

Ah! Well, I've used it with 30 and 50 watt VHF and UHF TX. When I bought it, a fellow ham warned me about some of them being quite noisy, but I have had no issues at all. For its size and price, it does a great job!de WJ8I
