On this page I give details of how to build two different versions of the Double Bazooka Antenna. Indoor Antenna Operating Tips. The first step is to identify the antenna connection on your TV, so you can make sure the antenna you have is compatible. If using long runs, use coax cable such as LMR-400 (pdf) rated coax cable. If your home is wired for cable TV and you want to drop cable in favor of a TV antenna the same coax cable can be used for the TV antenna. Make sure to ground the antenna using a grounding rod to protect your house from lightning strikes. At this point you will have a piece of coax hanging out the bottom of your antenna. The receiving element itself is a 33 inch 84cm square loop of the coax, so you will need to construct a suitably sized wooden frame, say 10mm (half an inch) less each side of the wooden dowelling around which you will wrap the coax - this is to make allowances for the coax which will then be the correct size. How to make or where to buy low power FM broadcast antennas Site analytics indicate many are searching for FM antenna information. Sounds like an antenna or coaxial cable. Handheld Police Scanner Antenna Good to Knows Some handheld antennas have an adjustable ‘elbow’ that allows the antenna to be vertical or horizontal. Coaxial connectors and adapters Reference pages to help you identify coaxial connector types. Can anyone tell me what the best sort of coax cable to use with a DAB antenna would be? I'm fitting a new antenna shortly and at the moment I'm using standard 75 ohm TV coax which I understand is ok for use with the Videologic DRX-701ES tuner as it accepts a 75 ohm input as does the antenna (3 element yagi). The Coaxial Trap Dipole is a symmetrical wire antenna whith traps at various points along the dipole arms to make them resonant at the required frequencies. If you require a long cable or are using a splitter, you may need a preamplifier. Features like polarization, type of poles like single dipoles or multipoles, product market feats, design, mounting, and cable length are very important considerations to choose one out of many. This wikiHow teaches you how to create your own FM antenna in order to increase your FM receiver's range. To construct the balun, mark RG-6 coax with tape at two spots 27″ apart (26″ for RG-59). Depending on your preferred range, you can do this by using either coaxial cable or speaker wire. To create this antenna you will need to measure the correct lengths for the sections and mark them. Simple ribbon type antenna (dipole) gives good performance in strong signal areas. FM Antenna Length Calculator Build a di-pole inside antenna and receive all the FM stations on your stereo unit, loud and clear. RST Engineering They have an antenna kit available to make up to 6 antennas utilizing copper sticky tape and toroid ferrite rings to fine tune the system. 8 - 30 MHz at full 200 Watts SSB/CW. to make a dipole antenna.
