I’d wager that at least 10-12 million people live within a 22 mile radius of Washington DC. ( The approximate distance to the horizon at 330 feet above sea level.) Is that a big enough audience? By the way, according to the internet, a1000 foot antenna gets you only 32 miles, not 45. Also, Florida is mostly flat and close to sea level, so part of that 1000 foot mast is to make up for being so near to sea level.
Outdoor FM Antenna
Unlike a few years ago not much options are available for a dedicated FM Broadcast antenna. Forget TV antenna that have no gain on FM ALI has inexpensive FM antennas with many elements but shipping is $150 to $260 dollars- too expensive. Wilson sells an FM antenna for $350- again too expensive. The only reasonable 4 cost option is Stellar Labs four element on eBay for $68 shipped. This horizontal mount antenna will receive full power FM stationers away with full quieting up to about 60 miles away in flat terrain. Two antennas could be bought taking the first two elements of one and use a 3/4" EMT conduit coupling attaching the two front elements to the four element to get 6 elements. This should receive FM stations to perhaps 80 miles away. For four elements 1 inch EMT for 15 foot length should be ok with 50 MPH winds. A wooden dowel inside the conduit in top section with mounting clamp at bottom 5 feet from house will allow much higher wind speed. EMT conduit is expensive thus two sections of 2" EMT costs about $135. The wood dowel is mandatory with 6 elements or use a roof mount tri-pod.

Population of the greater DC area which is certainly encompassed by a circle with a 22 mile radius is given as 6.3 million in 2023. But 22 miles would reach to towns south of Baltimore MD, and so the population reached would be greater than that of the greater DC area. As to antennae, make up your mind whether you’re talking about 1000 foot broadcast antennae or antennae that an audiophile might buy for home use. In that regard it’s quite likely you no more than I do, so have fun. |
You stated Washington DC that is 10 miles square not having 6.3 million people. 20 mile radius of Washington DC is 3.7 million not 6.3 million, .I am not changing radio station antenna length as they are normally 1000 to 1500 feet. Home antennas are limited to 100 feet. You been posting bad info consistently. FM antenna height by FCC. The average FM station antenna height is determined by the Height Above Average Terrain (HAAT), which is crucial for effective broadcasting.

Have a nice day. I have no idea what this was about or what you wanted from it. As to the population data, once again you put words in my mouth and then claim they were erroneous. I did not say anything about the square area of Washington DC proper. I did say that the census bureau says that the population of “the greater Washington area” was 6.2 million in 2023. And we are talking about a 22 mile radius (not area) at 330 feet. I trust you would agree that a broadcast antenna radiates signal in all directions typically. A circle with a 22 mile radius has an area of more than 1500 square miles. If you’ve ever been here you would know that DC is surrounded by densely populated towns in MD and VA, to account for most of the population of the greater DC area. |
