FM radio is not picking up many stations,,help

My in dash jensen radio in the motorhome is not getting FM radio stations well.

I can find a FM station in the pickup truck that is sitting beside the motorhome then try to pick up the same station in the motorhome and can't even with a higher FM antenna on the motorhome,,, Can anyone suggest something to try or a FM antenna booster,

Jimooo

Usually, with Fm, it's all about the antenna. Radio Shack or Best Buy.

No antenna or the antenna is disconnected. You really need to take the radio out and check things out.

I checked my rubber antenna is not broken and seems to be in good shape, the motorhome is only 4 years old. It seem to pick up more stations last year, have any of you all used an antenna booster for FM radio?

Why boost something that is partially broken? Tight connections with good ground work wonders.

The best test is to buy a cheap "universal" radio antenna, plug it into your radio, and hold the antenna outside of your RV. If the reception improves, it's your current antenna or cable. If no change, it's your radio.

FM antennas: compare prices and read reviews - Bing Shopping

Take your pick. Here is a list of FM antennas of every configuration and price.

But a good check of your own is a good idea and a best method. Good luck and let us know what you decide and how it works. Alway good to hear back.

Years ago when cars came only with AM radios they had these great long multi-section telescoping Radio antennas and I sat in a parking lot in Coldwater (Michigan) and listened to WABC in New York City. (Or WLS Chicago, Or WJR Detroit, or CKLW in WIndsor)

Then they started putting in AM/FM radios and suddenly the antenna was a fixed length, not nearly as good at long-distance reception, 3/4 meter long in case you wonder how long it is (arond 21 inches). 1/4 wave in the center of the FM radio band.

Now. . as it turns out a 1/4 wave whip (Really a half wave dipole with the body being the other half) is an "Ideal" antenna. anything shorter is comprimise.

The Rubber ducky is what, less than a foot tall?

That's the problem.

I represent ASA Electronics, the producer of the JENSEN brand of televisions, stereos and speakers, the Voyager brand of observation monitors and cameras and Advent appliances. At ASA, we strive to provide excellent customer service and product satisfaction and would like to offer some assistance in this matter.

Which model radio do you have? Typically, when you receive some signal, the antenna is the culprit. A radio that exhibited no reception, assuming the antenna and connections are good, might indicate a defective radio tuner.


It would appear that most likely the antenna and/or connections are failing, thus providing less signal strength than before. If everything passes a visual inspection, I would suggest testing with another antenna (not fully installed, just connected and positioned outside the coach) and see if reception improves. If so, replace the old antenna. Also, while the rubber antenna may be positioned higher than the antenna on your truck, a longer metal antenna will typically have more receiving capability. If the areas you frequent are typically rural and have weaker signal strength, you may want to consider such an antenna type for replacement, if your current antenna proves to be the issue.

Please let me know if I can assist further.

I have the same problem w/FM and AM radio stations. I can't seem to get them in, and if I do, they are spotty, here one minute and gone the next. I think my problem is that my antenna is on the rig hood underneath the cab-over in my Class C rig. In other words, I have limited reception. I've thought about trying to relocate my antenna; however, I haven't figured out how to do that. Anyone else tried moving their am/fm antenna to a new location?

As someone said it is all about the antenna, For FM a striaght length of wire, 3/4 meter long (About 29 inches) is the 'Reference" antenna, (This is over a ground plane)

Your rubber duck is what. perhaps 6 to 8 inches tall, of course it's 29 inches UNCOILED but it is still a seriously LOW POWER antenna and what's worse it very likely has no ground plane under it.

The ideal antenna is two 29" wires, one to center, one to shield, arraingned coax end to coax end

---------Coax------- Like that.

This, however, is not really practical and to be best there shoudl be some "Stuff" at the connection point (Balun)
