Can you use 2 FM transmitters at the same time?
Yes, it’s very possible
, and in fact, it’s quite commonly done in commercial FM broadcasting, in order to provide full coverage for major metropolitan areas.
Can multiple transmitters use the same antenna?
Duplexer definition:
A duplexer is a device that allows duplex operation a device to allow transmitters and receivers on slightly different frequencies on the same band to use the same antenna
.
What happens if you put radio stations that transmit the same frequency close to each other?
First, you can’t put stations on the same frequency that are too close together in a geographic area.
They will interfere with each other
. And for the same reason you can’t have two stations close together in frequency (close to each other on the radio dial) in the same area.
What is the maximum distance an FM transmitter can broadcast without a license?
How far will a 1000 watt FM transmitter reach?
| Watts in ERP Kilometers Rural area | 100 24 | 300 42 | 500 54 | 1000 76 |

An element of filtering is required if you want to use two transmitters with one antenna.
Diplexers allow either one radio to use two antennas, or two radios to share one antenna
. The diplexers have filters that prevent transmitted RF energy from traveling into the second radio and causing damage.
What is the difference between a splitter and a diplexer?
A Splitter.
You’ have probably noticed that diplexers and splitters look almost the same – both have one connection on one end and multiple connections on the other. The difference is that
a splitter takes in one signal and makes two out, while a diplexer or combiner takes in two signals and makes one out
.
Which is much better to use AM or FM Why?
Each FM station is allocated 150 kHz of bandwidth, which is 15 times that of an AM station. This means that
an FM station can transmit 15 times as much information as an AM station
and explains why music sounds so much better on FM.
Why do most AM stations power down at night?
Most AM radio stations are required by the FCC’s rules to reduce their power or cease operating at night
in order to avoid interference to other AM stations
. FCC rules governing the daytime and nighttime operation of AM radio stations are a consequence of the laws of physics.
How do you stop RF interference?
Keep cables as short as possible, and pay attention to routing
. A long cable not only increases power line common-impedance coupling (for unbalanced cables), but it also makes the cable a better antenna. Routing cables close to such ground planes as metal racks or concrete floors will reduce antenna effects.
Are FM transmitters illegal?
Part 15 certified FM transmitters can be used legally by anybody, anywhere in the U.S. without the need for a license
.
Do you need a license to use an FM transmitter?
How far will a 50 watt FM transmitter reach?
c) TRANSMITTER POWER.
If 50 Watt ERP is used, it’s very likely that
20 miles
of range will be achieved. This is because 50 Watt ERP is ample power to propagate a strong signal 20 miles. If a 1000 Watts of power is used, it is very likely that signal will only propagate just over 20 miles.
How can I increase the range of my radio transmitter?
In most cases, you
use transistors (and/or tubes) to amplify the RF signal from the transmitter
. Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna.
How do I extend the range of my FM transmitter?
What is the maximum range of FM?
The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to
15 kHz
(cf.
Can a CB antenna be used for FM radio?
| Model / SKU: Procomm IM-AF | Compatible with: All CB antennas |

How can I make my antenna splitter?
How does a diplexer work?
A diplexer is a passive (RF) filter component with three ports, which
enables the sharing of a common antenna between two distinct frequency bands
. This technology allows transmitters operating on different frequencies to use the same antenna and each band may both transmit and/or receive.
Why do I need a diplexer?
A diplexer is a device designed to take two signals from two different cables and intelligently put them on the same cable. A diplexer is the right thing to use
when trying to add an antenna signal to an existing cable
. There are many different kinds of diplexers. Passive diplexers are little more than combiners.
Can I use a splitter as a diplexer?
Thanks. It can be used in the other direction —
splitters are often used as combiners
. A diplexer takes one cable that is carrying all frequencies from, say, 5 MHz to 1500MHz and sends 5-862MHz out one port and 950-1500MHz out the other port. Or it is used to combine those separate bands of frequencies onto one cable.
How do I combine two digital antennas?
Combiners (which cost about $20) merge the two sets of signals into a single stream of TV. Using a combiner is as easy as
plugging the coax cables from the two antennas into the combiner device and then using a third coax cable from the combiner to connect to the Tablo OTA DVR or TV
. Easy peasy!
What is the difference between an AM wave and an FM wave?
The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
Why is AM radio not popular?
The decline in AM audio was
due more to regulation than to method of modulation
. One aspect of radio not understood by most listeners is the concept of occupied bandwidth, or the amount of spectrum that a station uses to transmit its signal.
Is AM radio cheaper than FM?
AM has poorer sound quality compared with FM, but is cheaper
and can be transmitted over long distances. It has a lower bandwidth so it can have more stations available in any frequency range.
Is AM radio dying?
Nevertheless,
AM radio has been in decline for years, with many AM stations going out of business each year
. Now there are only 4,684 left as of the end of 2015.
What is the most powerful radio station?
Beginning in the 1920s, Cincinnati businessman Powel Crosley, Jr., ventured into radio broadcasting, establishing
WLW, a Cincinnati radio station
. He increased the station’s broadcasting power to 500,000 watts, making it the most powerful station in the world.
Can a person hear radio waves?
Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz
(corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched).
Does aluminum foil block RF signals?
Does Wi-Fi interfere with RF?
RF interference can occur in your WLAN when 802.11 devices are trying to send packets and another device is sending a packet at the same time
. These interfering signals then disrupt your Wi-Fi service, leading to problems that the end-user experiences, decreasing performance and satisfaction with the network.
Do LED lights emit RF?
While there are cases of certain LED lamp products emitting RFI,
most LED lamps, especially those from reputable lighting manufacturers, are designed with sufficient RF suppression so as not to exhibit this problem
.
Can I turn my phone into a FM transmitter?
What’s the best radio station for FM transmitter?
Set the transmitter to broadcast on
89.9 FM
, tune your radio to that frequency, and you should hear your music. The transmitters are weak and can only broadcast a few feet. This is both good and bad. It’s good because you don’t want a transmitter in the car next to you on the highway to override your signal.
Does pirate radio still exist?
Pirate radio also continues
because legal open spots on the FM dial have been filled in since and because of the 1979 ruling, by both full-power and translator stations.
