LF Engineering H-800 Antenna - Again
I live in a townhouse. My best antenna is my rain gutter. I was not familiar
with the H-800 until the recent thread. My location is somewhat noisy. Is it reasonable to assume that I would be able to find a fairly quiet location inside my home for the H-800 since it is so compact and could easily be moved around my home to find a possible quiet location? I would like to try one on my Icom R75 but the antenna is not cheap. I don't think dealers normally accept returns on antennas. |

There are quite a few DIY projects on building active whips. They are
quite simple, though some people freak out when it comes to inductors. Even more compact than an amplified whip would be something like the Quantom ferrite loops. They are not as quite as a large aperture antenna like the wellbrook, but they are quite good for something you can put on a desktop. http://www.dxtools.com/ http://www.ramseyelectronics.com/dow...mz2006W-15.pdf http://www.palomar-engineers.com/Loo...p_antenna.html The only one I've seen used first hand is the Quantum. The null is decent. DeWayne wrote: I live in a townhouse. My best antenna is my rain gutter. I was not familiar with the H-800 until the recent thread. My location is somewhat noisy.

The advantages of an H800 over a garden variety active whip seem to be a cleaner amplifier and extra dynamic range. But it'll still do a beautiful job of picking up a nearby lamp dimmer. I think you could predict if it'll work for you with any active whip you might have or care to cobble together with $5 of parts from Radio Shaft. A portable mw radio tuned to a dead spot on the dial might also let you sniff for a quiet zone. If you do get an H800, spring for the extra $20 for bnc connectors on the antenna end so you can replace the coax when it dies. Someone else suggested the Quantum loop. I use one at my office with an HRB HW1390A receiver for MW reception. (it's a challenging location) I don't think the Quantum is rated for much beyond 2mhz. But if you want MW, the Quantum is a good choice. |

wrote in message ups.com... I think the idea is that, if you disguise the H-800 as part of a satellite antenna, no one from your Homeowner's Association will hassle you over it. Steve Got it- thanks, Dale W4OP |

First time I have ever heard of that one before,about using a satellite
dish antenna with a radio antenna.(you sure it won't pick up tv or ET?) The idea is unique and ufonious though. cuhulin |

Or, for that matter, it might just be so inconspicuous that no one
notices/complains, even if it is clear that it's not TV-related. Clamp it onto a ventilation pipe on the roof and I'll bet no one would ever even notice. A chimney might also work. Maybe even a near by tree. The H-800 can also be oriented horizontally, which opens up some additional possibilities. |

It is reallyhard to get high bandwidth with ferrite based loops. But
they are compact. The Wellbrook gets you wide bandwidth, but you really need at least a meter in diameter for the wellbrook to shine. Mark S. Holden wrote: DeWayne wrote: I live in a townhouse.

I don't think you would have a problem returning a whip antenna to 'Grove', provided all the packaging and literature are included. They have a good return policy. |

I recall someone posted a rather long technical explanation that there
is more noise that is vertically polarized than horizontally polarized. That is, noise will propagate better vertically polarized, which is why the whip is a bad idea. It may not be just an issue of finding a quiet spot, but the basic design might be flawed. HFguy wrote: DeWayne wrote: I live in a townhouse. My best antenna is my rain gutter.

Dale [W4OP] - CC&Rs :o) ~ RHF
What Are CC&Rs? The Covenants, Conditions and Restrictions (CC&Rs) Are the Governing Documents that Dictate how the Home Owners Association operates and what Rules the Owners -- and their Tenants and Guests -- must obey. http://www.realtor.com/BASICS/condos...sp?poe=realtor One of the few Legally recognized OutSide Antenna CC&R 'get arounds' (Loop Holes) are the small Dish Antennas used with Direct Distribution Satellite TV (DDS-TV) Broadcasting. NOTE - Some HOAs try to say that the development or building is wired for Cable and therefore the OutSide Dish Antenna is Not Allowed [.] - - - Oops then came DDS-TV of Foreign Cultural and Language Programs from Mexico, India, China, etc and the Ethnic (Racial) Discrimination Lawyers opened up the World to DDS-TV with a high percentage of Condo Balconies having a small Satellite Dish or two :o) Using the Dish with a small Active Antenna is just a way of getting around the CC&Rs and provides a fairly secure mounting structure for the Active Antenna. http://www.prosatellitesupply.com/im...-Inch_Dish.jpg http://images.amazon.com/images/P/B0...CLZZZZZZZ_.jpg http://www.powersecurityinstallation...llite_dish.jpg http://www.tomsnetworking.com/networ...s/img_2024.jpg http://altura.speedera.net/ccimg.cat...s/11862456.jpg http://www.skycasters.com/satellite-...llite-dish.jpg http://danny.oz.au/travel/mongolia/p...llite-dish.jpg http://www.kalyx.com/store/images/TERTRKS26.jpg Hey Why Not . . .
