Can you use a TV antenna for FM radio?

Partially guyed towers can be used e.g. when a very high tower for FM and TV transmission is required, which should also carry antennas for directional radio services in a much lower height. In this cases the antennas for directional radio services are mounted on the top of the free-standing part of the tower, while the guyed mast on its top carry the FM and TV antennas.
They can be also used in order to upgrade small stable towers (like watertowers) with a long antenna mast for FM and TV broadcasting.
However their use is rare, and done only in some European countries.

As WRGB has returned to channel 6, it has proposed an unconventional approach, by which it has requested to operate an analog FM radio transmitter at one edge of its digital TV allocation, using vertical polarization to retain compatibility with standard broadcast car radio receivers. According to WRGB's site, "We hope that the FCC will allow us to continue to operate on 87.7. We are building a unique transmitter for 87.7 that can operate simultaneously with our DTV signal on channel 6. TV transmissions always use horizontal antennas. Our new 87.7 transmitter will be vertically polarized. The use of vertical polarization for 87.7 will allow reception of our audio in a car radio or any other FM radio with a whip type antenna. "

Transmitting antennas for long and medium wave are usually implemented as a mast radiator. Similar antennas with smaller dimensions are used also for short wave transmitters, if these send in the round spray enterprise. For arranging radiation at free standing steel towers fastened planar arrays are used. Radio towers for UHF and TV transmitters can be implemented in principle as grounded constructions. Towers may be steel lattice masts or reinforced concrete towers with antennas mounted at the top. Some transmitting towers for UHF have high-altitude operating rooms and/or facilities such as restaurants and observation platforms, which are accessible by elevator. Such towers are usually called TV tower. For microwaves one frequently uses parabolic antennas. These can be set up for applications of radio relay links on transmitting towers for FM to special platforms. For example, large parabolic antennas ranging from 3 to 100 meters in diameter are necessary to pass on signals to television satellites and space vehicles. These plants, which can be used if necessary also as radio telescope, are established on free standing constructions, whereby there are also numerous special designs, like the radio telescope in Arecibo.

VHF/UHF television and radio signals are normally limited to a maximum "deep fringe" reception service area of approximately in areas where the broadcast spectrum is congested, and about 50 percent farther in the absence of interference. However, providing favourable atmospheric conditions are present, television and radio signals sometimes can be received hundreds or even thousands of miles outside their intended coverage area. These signals are often received using a large outdoor antenna system connected to a sensitive TV or FM receiver, although this may not always be the case. Many times smaller antennas and receivers such as those in vehicles will receive stations farther than normal depending on how favourable conditions are.

TV and FM (frequency modulated ) radio transmitter stations as well as transposer stations are almost always built on top of hills. A single station may have many transmitters both for TV and FM. In rare cases, each transmitter has an antenna system. But in stations where many transmitters are used, this is not always possible, so the outputs of transmitters transmitting in the same frequency band are combined by a diplexer and applied to a single antenna system. (i.e. VHF 1, VHF 2, VHF 3, UHF). If two or more antenna systems have to be used, higher frequency antennas are mounted higher on the antenna mast. (The sequence of antenna systems on a typical TV-FM station may be from bottom to top; VHF-2, VHF-3 and UHF.)
Microwave stations are also high altitude stations. Although high altitude is desirable also in GSM, the operators may use low power intracity stations for areas of high population density.

While only a limited number of local stations can normally be received at satisfactory signal strengths in any given area, tuning into other channels may reveal weaker signals from adjacent areas. More consistently strong signals, especially those accentuated by unusual atmospheric conditions, can be achieved by improving the antenna system. The development of interest in TV-FM DX as a hobby can arise after more distant signals are either intentionally or accidentally discovered, leading to a serious interest in improving the listener's antenna and receiving installation for the purpose of actively seeking long-range television and radio reception. The TV-FM DX hobby is somewhat similar to other radio/electronic related hobbies such as amateur radio, Medium Wave DX, or short-wave radio, and organisations such as the Worldwide TV-FM DX Association have developed to coordinate and foster the further study and enjoyment of VHF/UHF television and FM broadcast DX.

Löffelstelzen Transmitter is a broadcasting facility of SWR at Bad Mergentheim-Löffelstelzen in northern Baden-Württemberg, Germany. It was inaugurated at the beginning of the 1950s and used at those days a guyed mast, which was insulated against ground, because it was used for medium-wave broadcasting with a butterfly antenna for FM- and TV-transmission on its top. Later this mast was replaced by a concrete tower, which carried an antenna for FM-/TV-broadcasting on its top and a cage and a wire antenna for medium-wave broadcasting at its site.
This tower was replaced between 1998 and 2000 by a 179 metre tall concrete tower. This tower is not equipped with an antenna for medium wave broadcasting, because this was ceased in 2000 at the Löffelstelzen transmission site.

ERP for FM radio in the United States is always relative to a theoretical reference half-wave dipole antenna. (That is, when calculating ERP, the most direct approach is to work with antenna gain in dBd). To deal with antenna polarization, the Federal Communications Commission (FCC) lists ERP in both the horizontal and vertical measurements for FM and TV. Horizontal is the standard for both, but if the vertical ERP is larger it will be used instead.

The FM- and TV-mast Hosingen carries antennas at a height of 285 metres, pointed toward Germany. These antennas are used for transmitting the German-speaking program of RTL on 97,0 MHz with an ERP of 100 kW. The antennas for the transmission of the native radio station on 92,5 MHz with an ERP of 50 kW are mounted at a height of 237 metres. As transmission device for both frequencies, Telefunken S 3217 transmitters with an output power of 10 kW is used. For each frequency there is also a backup transmitter installed, with an output power of 10 kW, a Telefunken S 3152.

The W205 contains an FM radio with RDS and an integrated antenna. The ability is provided to record radio either onto the 5 MB of internal memory or up to 2GB of external memory to the Memory Stick Micro (M2) memory card. Such recordings can also be saved and used as ringtones. Activation of the FM radio requires a FastPort-compatible headset connected to the phone; the headset is required to function as an antenna.
