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! |
