highest gain hf antenna in the world
I was wondering what is the highest gain hf antenna thats operational
anywhere in the world? Secondly what is the gain. Peter |

... I was wondering what is the highest gain hf antenna thats operational anywhere in the world? Secondly what is the gain. Peter It is most likely the huge dish in Arecibo, Puerto Rico. Close by would be the HARP system in Alaska. Then the curtain arrays used by broadcast stations. Then the Rhombics, then the rest. -- Yuri Blanarovich, K3BU, VE3BMV |

Just for the heck of it , I did a little internet check on Arecibo and found the following info; ""Full operation of the facility ideally requires three frequency bands, near 3.175, 5.1, and 8.175 mhz."

Seems like Arecibo might have around 36dB gain at 28MHz where it is a
28 wavelength dish, at least according to scaling numbers I found on a random webpage. Not bad. Seems that a 3.5 wavelength dish (3.5MHz Arecibo) still has a bit of gain too. 15dB? I wish I had 15dBd gain on 3.5MHz... don't exactly want it straight up, though. 73, Dan N3OX |

Just hoist up one mountain, lower the other, and rotate the whole dish/valley onto its side. Paul Bunyan would have thought nothing of it. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

Harold KD5SAK i don't understand what this means? that they mix these freq's to get their usual super high seti freq xxxghz or what ever |
