FM Radio Station TRANSMITTER Set Up . How To Get It Right For Best Signal Quality.

- FM radio stations need a transmitter, antenna, cable and radio mast. Having this set up correctly can make the difference between a good radio signal and a bad one. This affects the signal range, signal strength and audio quality. Having the right transmitter set up can also affect your radio license. So it is very important that you get this right. In a licensed environment, it is either right or it should be switched off. In the listener environment, the quality can affect whether the listener stays tuned or listens at all.

Understanding how FM transmitters and antennas work is as important to licensed broadcasters as to pirate radio stations. Even hobby pirate broadcasters need to have a clear understanding of FM transmitters, FM antennas, broadcast signals, and FM signal power. Pirate radio stations often need an even better understanding as they need to both get the maximum out of their FM signal as well as know what will cause them to be detected as a result of their signal problems.
In this video, I discuss what affects how far your radio signal will go as well as how to make sure the signal is the best in radio and audio quality. There are certain things that affect your radio signal more than anything else and what makes your signal legal and what makes it in violation of your license agreement.
Most small and new radio stations have a very limited amount of signal power. If not used correctly, the signal can be wasted and not reach the intended listener. Many radio station listeners are moving around in their cars or on public transport. This means that the signal strength will fluctuate and may become unlistenable. To overcome this you need to be sure that the RF signal is used to its absolute best. There is no perfect solution but there are techniques that help to squeeze out the most signal strength and range as well as produce a better sound.
Once you have your radio station studio set up you will need to run your audio to the transmitter. That means either sending it via a radio link or connecting it directly to the transmitter.
Understanding the basic principals of radio signal distribution can change how successful your radio station signal can be. - Věda a technologie
MAKE SURE YOUR ANTENNA IS MATCHED TO YOUR PARTICULAR FREQUENCY. DEFINITELY INVEST IN QUALITY FEEDLINE & CONNECTORS, WRAP YOUR EXTERIOR CONNECTIONS FROM THE ELEMENTS. GREAT VIDEO! CHEERS!
Hi Thank you. Yes that's right. For the antenna to be resonant it needs to be matched to the transmitter frequency then fine tuned. You are also right about protecting your connectors from the elements. Many low power radio stations don't realize that their weak signal could be because there is water in the connector or rust after a long while. Additionally what I didn't mention is lighting protection. I lost a transmitters once for not having it protected. It's quite affordable and can save a fortune in transmitter equipment. Thanks for your comment. Glad you enjoying the videos :) Cheers
@@inspiresoundpro Yes lightning/EMP protection is important. There is more to getting a station on the air properly than most people realize. They buy a cheap piece of junk transmitter from china, connect an antenna and think they are now a radio station.
@@sw6188 Oh yeah there is so much that goes into it. The problem is that a lot of it is just hard work and bits of gear nobody cares about. So it's not always worth making a video about it because most people just want a fun fast look at things. The stuff that makes up a radio station can often be as boring as dry sand. But it can be as important as any part of the station. If I, for example, talk about balanced vs unbalanced audio cables in the studio, their eyes roll into the back of their heads. So, lol, yeah I guess some things need to be learned the hard way. Cheers. Happy New Year!
Interesting video and mostly correct (I am a broadcast engineer). Just one thing, please don't say "dBs" (dbeez). It is never dBs, only ever 'dB' regardless of the number.
Lol you are absolutely right. It's an old habit from working in the two-way radio industry. I know it should be deebee but I guess old habits die hard. I will do my best to say it correctly in future videos lol. Happy New Year!
Thank you for information I shall forward this to my management at our Community radio Station.
Excellent! Glad you enjoyed the video. Cheers.
Wat snel!! dank je wel voor de super snelle reactie , ga er zeker wat mee doen , DANK !!!! Gerrit.
Heel graag gedaan. Heb een geweldige dag :)
You are very welcome. Have an awesome day :)
Hallo, wat een fijne site, daar leer ik elke keer weer war van super, nu mij vraag, hoe lang met mijn antenne zijn om uit te gaan zenden op 88.1 in de Fm band?
Hallo. Bedankt voor je mooie compliment. Ik hou ervan als mensen genieten van mijn video's :) De lengte voor een halve golfantenne op 88,1 Mhz is 170,144 cm. Voor een kwart golflengte is dat 85,072 cm. Bekijk mijn video over het afstemmen van antennes. Het zal u laten zien hoe u elke antennelengte uit uw frequentie kunt berekenen.

Hello. Thank you for your nice compliment. I love it when people enjoy my videos :) The length for a half wave antenna at 88.1 Mhz is 170.144 cm. For a quarter wavelength it is 85.072 cm. Check out my video on antenna tuning. It will show you how to calculate any antenna length from your frequency.

Goedendag, weer even een vraagje, hoe lang moeten de radialen zijn bij een antenne lengte van +/_ 85cm ?
De grondvlaklengte voor een halve golf dipool of kwartgolfantenne is een kwart golflengte lang, dus als je een antenne maakt voor 88 MHz op ongeveer 85,2 cm, dan moet het grondvlak even lang of langer zijn. Bekijk mijn video over het afstemmen van antennes.
czcams.com/video/WOGX70-kIYA/video.html
Het zal een stuk beter uitleggen. Maar het korte antwoord is dat de grondvlakken minstens zo lang zijn als de belangrijkste radiale lengte van een kwart golf, maar om de antenne verstelbaar te maken van 88 tot 108 MHz, maak de grondvlakken de langste lengte van 85,2 cm.

The ground plane length for half wave dipole or quarter wave antenna is a quarter of a wavelength long so if you make an antenna for 88 MHz at about 85.2 cm then the ground plane should be the same length or longer. Check out my video about tuning antennas. It will explain a lot better. But the short answer is that the ground planes are at least as long as the main radial length of a quarter wave but to make the antenna adjustable from 88 to 108 MHz make the ground planes the longest length of 85.2 cm.

Thank you. I'm glad you enjoyed the video.
Hello sir please give me a suggestion. I have a 7 watt transmitter and it has a stock 50 ohm telescopic antenna.
Now my question is.. Can I use my transmitter for 2-3 hours continuously with that antenna?
Someone told that if use telescopic ( stock antenna) my transmitter will burn within 30 minutes.😢 Is it true? Please reply..
Please see the answer I gave you on other video
hello. Whats that Town called thats surrounded by Hills ?
thanks
Hi. It is a place called Patscherkofel. The transmitter is on Innsbruck Mountain in Austria.
Which type of cables? You mean coaxial cable? What is the function
Hi. Thanks for your comment. Yeah, I made a video about the coaxial cables and the connectors to use. Check it out here czcams.com/video/CNtRaqKhdoY/video.html
It help you with that.
RG58 is excellent for most applications.
@@christopherhulse8385 Yes RG58 is great for short cables of just a few meters but for longer high-power signals RG213 and LMR cables are better.
This is laughable. As a former station owner (one FM and two AM's licensed by the FCC), this whole thing is ridiculous. No real FM station would use a transmitter that you could fit in the palm of your hand. Transmitters (and antennas) used by licensed broadcast facilities must be "FCC type accepted"; the transmitter he's holding in his hand certainly is not! Using an antenna not tuned to your assigned frequency is just asking for a visit from the FCC; you'd very likely be creating interference!
If you're setting up a Part-15 FM station, go for it, but don't use an illegal transmitter, exceed authorized power, or use some home-brew antenna setup. Keep it legal--the FCC don't play when it comes to this stuff!
Funny how the ones who claimed other's info to be laughable, say things as lame as an untuned antenna causes interference. Think you need to go reeducate yourself a bit. The only thing an unturned antenna can do is give a lower level signal. Interference comes from harmonics which antennas cannot create. The discussion about the antennas has nothing to do with the FCC or Part-15 stations. You might not know this but there are other countries in the world besides the USA. There are low power radio stations licensed around the world that have nothing to do with Part-15
