wahroonga farm Posted January 24, 2007 Share Posted January 24, 2007 There's useful info in the following links. Unlikely you'll be using a true rhombic for TV, but rabbits ears may approximate some of the principles. In reality most antennas are a jumble of some/all of them to achieve the very broad frequency response demanded by the TV spectrum. http://www.dtvforum.info/index.php?showtopic=12098 http://www.dtvforum.info/index.php?showtopic=37372 Link to comment Share on other sites More sharing options...
alanh Posted January 25, 2007 Share Posted January 25, 2007 wahroonga farm, Thanks for the links, rabbits ears are just a dipole. If you want a rhombic, it is diamond shaped with the connection on one end and a resistor on the opposite end. AlanH Link to comment Share on other sites More sharing options...
piupster Posted February 3, 2007 Share Posted February 3, 2007 (edited) Hi, This probably is being posted in the wrong place but really hoping someone could help me out. We moved into our house 3 years ago and noticed a wierd looking tv antenna on the roof in addition to the normal free to air antenna. We also have a point near the tv and the plastic cover says FM/TV ? Does anyone know what this is , what it is used for and how it gets connected to your television ?

Regards Chris Cris, The TV/FM plate is used to connect a TV and an FM radio tuner to the repsective connectors. It simply separates the FM signal which is received from your TV antenna. As for your 'weird looking' antenna, if you describe it, or better still, post some pics of it, we may then be able to advise what it is. Link to comment Share on other sites More sharing options...
