antenna How does a folded dipole work? - Amateur Radio
The folded dipole is also a loop antenna, but in normal configurations the electric dipole radiation is orders of magnitude larger than the magnetic dipole radiation. The electric dipole radiation pattern has a zero in the plane of the dipole while the magnetic dipole pattern (a doughnut) does radiate in the plane of the (folded) dipole. In case you make your "folded dipole" a circle to give... In radio and telecommunications a dipole antenna or doublet A common construction is to make the arms of the folded dipole out of twin lead also, shorted at their ends. This flexible antenna can be conveniently taped or nailed to walls, following the contours of mouldings. Shortwave antenna. Horizontal wire dipole antennas are popular for use on the HF shortwave bands, both for

how i can make folded dipole antenna? Yahoo Answers

Now, from my understanding, the impedance of a folded dipole is based on the theoretical radiation resistance of a dipole (73 ohm) multiplied by 4 since folded. This is roughly 300 ohm and does not depends on the cable itself....
2 Meter Vertical Dipole Antenna I was looking to build an easy to breakdown 2 meter antenna for an event I was helping with. I have issues with J-poles, and while easy to build, I think they interact with their feedlines way to much. 1/4 wave ground planes work well, but will have half the signal of a dipole.

How To Make A Folded Dipole Antenna

Amateur Radio (G3TXQ) - Folded dipoles A. Introduction. A recent interest in "bent" half-wave dipoles led me to look into the theory of the classic Folded Dipole (FD) in some depth. Dipoles bent into a square shape - for example those used in the CobWebb Antenna design - typically exhibit a low feedpoint impedance of around 12Ω and it is convenient to use the impedance transformation

  • The Code 411 Terminated Folded Dipole Antenna is a 2-wire antenna designed for broadband operation in fixed stations. Separate variations are available to support power levels of 125 or 1000 W. The Code 411 Antenna can be mounted horizontally between two support systems, or as an inverted “V” using a single central support mast.

  • A Folded diapole antenna has a central impedance of 300 Ohms and thus, you will need a ladder line or a straight cable to take the feed to the receiver or a transmitter. But now a days ladder line are not much used and you will find a lot of coax cables in the market that are found cheap. But to make direct connections to the antenna will not be a proper way as the coax cables have impedance
  • Now, from my understanding, the impedance of a folded dipole is based on the theoretical radiation resistance of a dipole (73 ohm) multiplied by 4 since folded. This is roughly 300 ohm and does not depends on the cable itself.
