WWV =http://tf.nist.gov/timefreq/stations/wwv.html =OR= The 'sister' Time Signal Radio Station WWVH in Hawaii NIST Radio Station WWVH located on the Island of Kauai, Hawaii, WWVH =http://tf.nist.gov/timefreq/stations/wwvh.htm A WWV Time Signal "Half-Wave" 10 MHz Dipole Antennahttp://www.angelfire.com/mb/amandx/dipole.html would be 46.8 Feet Tip-to-Tip {46' 10"} and have Two 'equal' Arms of 23.4 Feet {23' 5"} Mounted about at least 24 Feet above ground level. *Use at least a 50 Foot long piece of Coax Cable -or- Balance-Line for the feed-in-line from the Antenna to the Radio/Receiver. FWIW - Some "Time Signal Freaks" simply use a simple Dipole Antenna made from 100 Feet of 300 Ohm TV type Twin Lead with 47 Feet for the Twin Wire Antenna Element and the other 53 Feet for the Balanced feed-in-line. The Twin Wire Antenna Element is 'wired' as a "Folded" Dipole Antenna and the feed-in-line is 'wired' as a Balanced Pair. * *Here are some "Folded Dipole Antenna" WebPages :http://www.qsl.net/w4sat/fdipole.htm...ak.com/antenna... * *Basically since this Folded Dipole Antenna is made of 300 Ohm Twin Lead with a very smal 1/4 Inch "Spacing" between the Two {Twin} Wires; and for its Length of 47 Feet; and 10 Mhz Frequency; and the small Size of the Wire 'cutting' it to the Length of a standard Dipole Antenna is OK RadioShack 300-Ohm [Flat] Twin-Lead @ 100 Feet RadioShack Catalog # 15-1175http://www.radioshack.com/product/index.jsp?productId=2049618&cp TIP - This is also a good 'back-up' Antenna for general Shortwave Listening (SWL) and for those who have Two (2) Antenna Connections on the back of their Shortwave Radio Receiver : one SO-239 Jack [ 50 Ohm LO-Z] and a Set of Twin Terminals [ 500 Ohm HI-Z]. This Twin Lead Folded Dipole Antenna 'cut' for 10 MHz with a Balanced Twin Lead feed-in-line makes a good always ready -and- a good "Reference" Antenna to compare your latest new Antenna or Antenna Modification to your main [primary] Shortwave Listening (SWL) Antenna.

NOW "ABOUT" WWV in Fort Collins, Colorado, USofA WWV =http://tf.nist.gov/timefreq/stations/wwv.html -aka- NIST Radio Station WWV Located about about 100 kilometers north of Denver, CO. WWV =http://tf.nist.gov/timefreq/stations/wwv.html * *The WWV Radio Station Radiates 10,000 Watts {10 kW} on 5, 10, and 15 MHz; and 2500 Watts on 2.5 and 20 MHz in the Shortwave {High Frequency} Band. WWV =http://tf.nist.gov/timefreq/stations/wwv.html * *Each WWV Radio Station Frequency is Broadcast from a Separate Transmitter and Antenna. *Although each Frequency carries the same Information, multiple frequencies are used because the quality of Shortwave Radio (HF) reception depends on many factors such as location, time of year, time of day, the frequency being used, and atmospheric and ionospheric propagation conditions. The variety of Frequencies makes it likely that at least one Frequency will be usable at all times. WWV =http://tf.nist.gov/timefreq/stations/wwv.html WWV and WWVH Radio Signal Modulation The Radio Signals Broadcast by WWV and WWVH use Double Sideband Amplitude Modu*lation {Both the Upper and Lower SideBands "DSB"}. WWV =http://tf.nist.gov/timefreq/stations/wwv.html The WWV and WWVH Signal Modulation Level is 50 Percent for the Steady Tones, 50 Percent for the BCD Time Code, 100 Percent for the Second {Sound} Pulses and the Minute and Hour {Sound} Markers, and 75 Percent for the Voice {Time} Announcements.
