FM antenna is not providing reception, despite cable connected to powered antenna amplifier. TV also connected to powered antenna amplifier (splitter) works fine. FM mode produces only static. I purchased the Denon as a floor model from Circuit City (now defunct); am just nowtrying the FM. Could it have been defective, or am I not setting it up properly? CD works fine. I have not tried the XM. Thanks for any advice!

Television signals are at such high frequencoies they will be reflected form buildings and other objects, and attentuated by moisture in the air and through the leqaves of trees, etc. In large cities yourt TV singals can arrive from different paths Digital TV signals bounce as di the old "analog TV" signals but the technology allows the receiver to ignor singals that are out of phase so the picture is "clean" despite multipleversions of the signal arriving at the antenna at slightly different times. That said, if the signal is weak, there is little you can do other than experimanet with positioning the receivng antenna. Typically, building walls attentuate televisoin signals so locating the receving antenna close to a window often provides for stronger signal reception.

Amplified antennas cannot amplify what is not there. Moisture in the form of fog, rain and snow will attenuate television signals and if thre signals are marginal in good weather, they may be virtually not-existent in wet weather. Digital TV signals are threshold dependent. When they are toow eak, you won't see anything. Back in the old analog TV days, you could see a "snowy picture" but digital TV doesn't allow for that. The signal is either strong enough to be viewed or it is not.

You have few real options if you do not subscribe to cable or a satellite tv provider. Amplified antennas can help but if you need them you live in a marginal TV reception area to begin with and more prone to the vagaries of weather and the seasons.

That sounds like the description of a broadband amplifier. It likely has "F" type (cable-coax) connectors and a power cord.
Commonly used to increase the signal level of TV cable to compensate for inserting a signal splitter, or in some cases to increase the signal level from an antenna, typically outdoor TV or FM radio antenna, so it is connected between the signal source (antenna, or cable) and receiver with antenna as input and receiver connected to the output of this little box. The gain (amplification) it provides is 12 dB, so the output is more than 3 times the input.

INSTALLATION

Channel Master by PCT indoor antennas are designed to provide optimum reception of

UHF / VHF and FM signals. These antennas have 75 ohm outputs, which allow simple,

hassle-free connections to today's newer TV sets that have 75 ohm F type connector

inputs.

Simply attach one end of the supplied 6' cable with F connectors to the output of the

antenna (Fig.1). Attach the other end of the cable to the input of the TV set or VCR

(Fig. 2). Some adjustment of the antenna might be necessary for optimum viewing.

Model CM-4030 includes a built-in amplifier and separate power supply.

1. Follow the same steps as above for antenna to TV / VCR hookup. Note : Model

CM-4030 also allows for two set / VCR hookups with its unique dual output feature.

2. Insert the power injector into the back of the antenna (Fig. 3). Plug in the power
transformer to the closest electrical outlet (Fig. 4).

Single Stranded wire ( AWG # 22 ) can be used as an antenna


• For FM reception : any length from 1m to 5 m will work.

provided that there are FM stations near your area.


• VHF TV antenna can be used for a clearer reception with

RG 59 cable




• For AM band reception, it would be longer than 5m

You need to connect the radio antennae properly using the coaxial or the ribbon wire to the antenae so to get the best FM reception.
If this is not connected do so from the rear of the tuner/amplifier.

FM reception is weak

What to do

• Extend the power cord as much as possible. The FM antenna is in the power cord.

• Move the power cord to adjust the FM antenna

• If you still have problems with FM reception, you may need an external antenna.

* Call Bose®Customer Service to request one.

The external antenna on your radio is a coax (round) design It needs an adaptor and an antenna which are cheap.

Easy to make, radio shack "F" connector 90 degrees or straight, to 300 ohm wire connections. Attatch a 300 ohm flat ribbon antenna cable to those two screws and plug into radio and see how your reception is. You will need to position the antenna wires to get best reception. I have hid them in back of paintings and so on.

Cheapest solution next to putting an extension cord on radio power cord.

First of all check for any nearby source of interference.....Move your unit away from all computers, fluorescent lights, neon lights, microwaves, cell phones, and cell phone chargers. These devises tend to produce noise in the medium frequency band, where AM radio is broadcast.
If the unit plugs into the wall with a nonpolarized plug (where both prongs are the same size), try reversing the plug in the outlet. Moving the plug to another outlet might help, too.
check for fault in the antenna lead, (common) or bad earth on the antenna to body
If you don't have an antenna connected to your FM receiver,With a receiver or tuner, connect a wire-loop or T-shaped dipole FM antenna to the back of your unit. Move the antenna until you get the cleanest signal. Use a signal-strength meter or display to gauge signal strength if your unit has one.

Step 2 If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.

Step 3 If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.

Step 4 If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.

Step 5 Temporarily switch to monaural mode to improve a weak signal on an FM receiver.

HI there,

Well Yes you can improve the reception, please follow the below steps -

Improve FM Radio Reception -
 
1. If you don't have an antenna connected to your FM receiver, purchase a simple dipole antenna--a simple T-shape flexible wire-- and connect it to the FM antenna inputs on the receiver. Because FM signals are directional, you'll want to experiment with the positioning of the wire to find the best reception of the station you're trying to receive.
 
2. If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.
 
3. If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.
 
4. If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.
 
5. Temporarily switch to monaural mode to improve a weak signal on an FM receiver.


Improve AM Reception -
 
1. Gradually rotate the radio 360 degrees. Leave it in the position where it sounds best.
 
2. Reverse the AC plug if it isn't polarized. (If you can flip the plug over, then it's non-polarized.)
 
3. Plug the radio into a different AC outlet.
 
4. Move the radio closer to a window.
 
5. Experiment to learn if appliances and powered products in your home are causing interference: computer monitor, television, electric blanket, light dimmer, fluorescent light, hair dryer, air conditioner, smoke detector. If possible, turn off the offending item. Otherwise, move the radio to another room.
 
6. Upgrade to an external antenna if your receiver, tuner or radio has a place to connect one.
 
7. Buy a passive AM antenna that doesn't need to be connected to a radio or receiver.

Good Luck!!

Thanks

If you used the 2 plug nissan radio harness, there should be a blue wire on there which is the (power antenna) even if your car doesn't have a power antenna, this wire needs to be connect to power on the am/fm amplified ant which is used in many nissan cars.

if the jensen has a blue or a blue/white wire, connect it to one of those. if not, you can always connect it to the red ACC wire. that should solve your reception problem..

hope this helps

Is it just a single wire?

If so, purchase a cheap FM antena. It looks like a "T" when spread out (4' to 5'). That should help.

You can purchase an "amplified" antenna, but if your area reception is really bad (such as in a valley) the antenna would just amplify the noise as well. Look for web based radio in this case or if you have cable there are stations on it.
