My name is Michael, KB9VBR, and I carry a full line of VHF and UHF antennas for sale. I specialize in a certain type of antenna called a J-Pole. The J-Pole antenna is a 1/2 wave antenna with a 1/4 wave matching stub. Sounds complicated, but it really isn't. The great thing about J-Pole antennas is their simple design and excellent performance A half-wave dipole has close to 75 ohm impedance, so it is very easy to connect using 75 ohm coaxial cable to an IEC connector. One way to construct this antenna is to get a ready made IEC interconnect cable that fits your receiver
Its much more complicated than that and can result in noticeable loss in many cases. Besides the calculated loss using a 50 ohm matched antenna and radio designed for 50 ohms with a 75 ohm feed line, depending on the length of the 75 ohm feed line it can turn into a matching transformer to some other odd impedance with additional losses receiving antenna. Again, changing from the 50-ohm RG-213 to a 75-ohm RG- 11/U makes no difference on any of the receivers I've tried. 75~2 coax to antenna Figure I. The cotangent transformer. Two ,081-wavelengthpieces of coax, one 50-ohm and the other 75-ohm, connected as shown, allow yo Tips for Improving FM Reception. but location of the radio and the antenna are more important than the type of antenna.

The Flying V Antenna - A Directional Dipole with 50 Ohm Feed Impedance A special report from LowPowerRadio.blogspot.com - learn how to set up your own radio station! A half wave dipole at FM broadcast frequencies will often have a feed impedance of around 75 Ohms I think there are a couple of effects that get mixed together a lot of times. Impedance Mismatch-- Any time you have an impedance mismatch at an interface, some of the signal is reflected back down the line, while the rest is passed through the interface.On a 75-to-50 interface (or 50-to-75), 4% of the signal is reflected back toward the source while 96% continues to the destination FM aerial inputs are either 75 ohm coax, or 200 Ohm screw type with two screws. A lot have both terminations. If you just have the 300 ohm then you can get a balun to convert from 75 to 200 ohm. There is no one wire FM connection. Last edited: Dec 26, 2015. Audioholic Overlord. No FM antennas are single wire. That must be the AM antenna you are.
Yes, a dipole has a feedpoint impedance of 75 Ohms in free-space. Your dipole will not be in free-space but over real ground. On 75 meters, if it is less than 50-60 feet high, it will probably have a feedpoint impedance closer to 50 Ohms than 75. Even if it did turn out to be 75 Ohms, the mismatch is not worth worrying about. ssbothwell SWL FM Antenna 75 Ohm For Yamaha Natural Sound Stereo Receiver, Radio Audio Signal 4.5 out of 5 stars 10 product ratings 10 product ratings - FM Antenna 75 Ohm For Yamaha Natural Sound Stereo Receiver, Radio Audio Signa These inventions simply use the ever popular 300 Ohm antenna lead in wire. You can use them for any frequency, including the HF bands, but you will need a tall tower, or a high tree to hang them high in the sky. As of this writing, 300 Ohm antenna wire is pretty scarce. A roll of 300 or 450 Ohm antenna wire was $55.00 just a year ago The dipole is customarily an electrical half wavelength of wire at the frequency of interest, since the impedance under this condition is theoretically 72 ohms resistive and is a good match to a 50-75 ohm source or load generally presented by interfacing equipment such as receivers and transmitters designed to work into this range of impedances
If the shield is good, then all that matters is how well the coax matches your antenna. There's lots of 75 ohm antennas, so you'd then just need a 75-50 ohm balun to match it to your radio or a good antenna tuner. Also, as several others pointed out, you can make a nice hairpin match or a 300-50 ohm balun with 75 ohm coax The Impedance of the various devices being connected as well as the Coaxial Cable itself must match. So if you are, for instance, connecting a 75 Ohm video camera connection to a studio monitor, the coaxial cable must also be 75 Ohm AND the connectors on the coaxial cable (i.e. BNC connectors) must be 75 Ohm in Impedance 1PCS FM Radio Antenna 75 Ohm Dipole Indoor T Antennas HD Aerial Male Type F Connector For FM Radio Indoor use for YAMAHA HOT.

Hardly enough to worry about. Of course that ASSumes that the radio and the antenna are actually 50 ohms. That is a good assumption for well designed transmitters and a fair assumption for relatively narrow-band antennas While some hams use RG6 and 75 ohm hardline sucessfully, there will always be a mismatch between the 75 ohm coax and the 50 ohm output of the radio. This may be acceptable in some circumstances, but not in others. A 1.5:1 VSWR is not that bad, but if your antenna does not have a 1:1 VSWR at the operating frequency, it could be a problem

Typical radio equipment is designed for 50 ohm load impedance, so we usually use 50 ohm cables and build or buy antennas that are specified for 50 ohm. While most cables have a flat impedance over frequency (they measure 50 ohm at all frequencies you are likely to use), the same is not true of the antennas 50 ohm (or 75 ohm) coaxial wire with copper shielding; waves then travel long distances, carrying the sounds, songs, talk, etc. you're familiar with on radio. A receiver antenna (on your radio, for example) captures the radio waves that have been transmitted, and the electric current generated is converted by your radio into the sounds. All I needed to fabricate is a replacement 50 ohm coax 1 wave in length and a 1/4 wave length of 75 ohm coax. I had LMR-240 Ultraflex on hand for the 50 ohm piece. DX Engineering promptly shipped my piece of RG11 along with some solder type UHF connectors foam. This antenna is 140 ohms or so both on 14mhz and 18 mhz.
