Ahhh . . . so I have this VHF radio with an antenna high atop my mast.
Can I tap into that antenna for a TV? Seems like it should work. Scout |
well, duh
Yes, but the multipath will kill your TV picture. TV's require highly directional antenna to reduce the reception of multiple reflected signals. These reflected signals add "ghosts" and fades to your TV signal. If there is HDTV in your area a coat hanger would work for the signal. HDTV signals are digital whereas the regular TV signals are analog. The marine antenna may not work well on higher channels, it depends on its guts. What brand and model is the antenna?
The method of tapping is important as you do not want to transmit the VHF signal directly into your TV set. I would use a directional coupler with 20-30 of coupling. Use the direct ports for the VHF and use the coupled port to couple from the antenna, not the VHF radio. You could also try a signal splitter with a large 1Kohm resistor in series with the TV line. You may get a crap picture with this set up. "Scout" wrote in message . .. Ahhh . . . so I have this VHF radio with an antenna high atop my mast. Can I tap into that antenna for a TV?

Scout I saw the *well, duh* so I thought it was something I could answer. :-) But I'm clueless about antennas and radios and TVs. I don't have them on my boat. I don't want them on my boat. A little boom box with CD player is all I need. I know how to put new batteries in.... Cheers, Ellen |

Scout I use a special splitter to share the FM with the VHF radio. IIRC, it has the logic to shut down the FM side when the VHF side is transmitting. Or maybe that was the excuse to get me to pay $15 for it. For the TV we use the larger Shakespeare "disc" style omni directional antennae that comes with an amplifier. It does a good job of pulling in stations from 50 miles away. It is, however, 8 year old technology. |

Its on the mast, under the radar. http://www.sv-loki.com/Summer_06/Misery_Cove-1.jpg At this frequency, height is important, so being able to elevate it some is important. On our previous boat, we used the smaller version, but rather than attach it to the mast, we laid it out on the boom, as high as we could get. The results were mixed. A Practical Sailer review claimed the 21 inch disk was much better than the 14, but again, this is old info. Much depends on your needs and location, so the first thing to try is some very cheap solution, such as the wire "T" that comes with FM radios. |

Apparently it wipes out GPS units for nearly 1/2 mile. There was no general recall, and the problem only affect several hundred units, none of them were omnidirectional. Marine Safety, Security and Environmental Protection November 15, 2002 Washington, DC It has come to the attention of the U.S. Coast Guard and Federal Communications Commission that certain consumer electronics-grade active VHF/UHF marine television antennas are causing operational degradation in the performance of Global Positioning System (GPS) receivers. This interference may be realized as a display of inaccurate position information or a complete loss of GPS receiver acquisition and tracking ability. The interference is not limited to the GPS equipment onboard the vessel with the installed active marine television antennae. There have been reports of interference occurring on other vessels and installations operating up to 2000 feet away from vessels using such antennas. In one particular case, the interference caused the position of the vessel as displayed on the electronic chart to move erratically and dramatically often across large expanses of land. As can be expected, various data displays indicated erroneous information such as excessive speeds. In these instances the problem would occasionally correct itself while at other times required resetting the system. To the vessel's crew these annoyances were frustrating and caused concerns that perhaps less obvious inaccuracies were occurring. Ultimately this affected their confidence in the performance of the GPS and Electronic Chart Display and Information System. If you are experiencing recurring outages or degradation of your GPS receiver operation you should perform an on-off test of your TV antenna. If turning off the power to the antenna results in improvement in the GPS receiver performance, the antenna may be the source of interference in the GPS band. In that case, you should contact the manufacturer of the antenna and identify the symptoms.

Actually, Shakespeare jumped on the problem very quickly, and notified the CG that the original report was flawed within a few weeks. And the problem was isolated to a small number of units. I'm guessing it was something like bad shielding in one of the components within the amplifier. |

How would you like the multipole expansion of an infinitesimal dipole versus the infinitesimal folded dipole? I could show the fundamental differences in the E and H fields for the inverse radial terms for each antenna. Or would you just prefer a brute force numerical moment method solution? Oh look Krusty! Here are the fields of an infinitesimal folded dipole (loop): http://www.ece.msstate.edu/~donohoe/ece4990notes5.pdf What's really neat is it is done with magnetic vector potentials. Back when you took physics they probably taught you the myth that magnetic vector potentials are fictituous quantities only used for ease of calculation. But guess what? The results of the famous Arahanov-Bohm Experiment clearly show that the magnetic vector potential is real! Neat, isn't it? Exciting too! Back to the link! It also compares the E and H components of a dipole and a loop (folded dipole). Note the fields of the dipole are in phase quadrature to the folded dipole type antenna! That's that j term in the front. Remember I talked about the DC impedance? They are also in phase quadrature too! Small world isn't it?

I know who you are. What does it matter? I wouldn't reveal it here ever. I respect your privacy and know in real life you are a decent person. The truth is, you can't reveal who I am... and for a very good reason. CWM Ah...so you're just another Gilly sockpuppet? |

For some reason, Red Cloud has decided to use himself as a perfect example. He immediately 'feels' I was discussing dielectrics. Of course I was not. But then he knows because he 'feels' that is what I must have been thinking. So why does Red Cloud do this? Just another name and reason to insult others. His name? Red Cloud® posted using numerous names including , Ekal Bnek, MaximumSmoke, and . One poster even speculates that BinaryBill also posted using the name Ken Blake. He has been accused by Sirius, VWWall, Thor, etc of using pseudo names. In a discussion entitled "Computer Fire Starts Flame War" in alt.computer, others bluntly ask him (whoever he really is) what his alter egos would think. Previous posts by BinaryBill - now Red Cloud® - of insults are cited in that alt.computer discussion at: http://tinyurl.com/bjk8e ============ He even claimed to work with Grace Hopper on the original computer called Eniac in the 1940s. Therefore he must know something... about twisting the truth. |
