, I'd like to improve reception within the cabin. I'm planning on buying one of those yagi antennas, which I've read good things about. First question is size/cost. A 20" yagi (12db gain) runs about $70. Other available sizes include 40" (24db) for $100 and 60" (36db) for $130. I'd prefer to have the smallest antenna possible since they aren't the most attractive things in the world to have sticking off your cabin. But I guess under the circumstances it would probably make sense to just spend the extra $60 since it's better to have more gain even though you might not need it.|
Originally posted by coyotefred Hello! I'm trying to improve the reception of my cellphone (LG LX5450) on the alltel network in northwest Nebraska to a remote cabin.

On those days I don't want to hike the hill , I'd like to improve reception within the cabin. I'm planning on buying one of those yagi antennas, which I've read good things about.

I have no idea whether a yagi mounted on the cabin roof would be good enough. When I stand up there (on the roof) with the phone now I get a slightly improved signal compared to inside the cabin, but still not reliable. Or should I mount the yagi up that hill aways and make a long run of coax to the cabin? The antenna location would obviously be better, but would I lose what I've gained as far as signal loss by the long coax run? The run would probably end up being 150-200' or so. 'Any thoughts/advice appreciated! |

Originally posted by Life-Is-Good If you get a Yagi be sure to try pointing it in ALL directions to find the best signal. You never know what object might be reflecting the best signal in your direction, especially trees. My Yagi actually gets the best signal when pointing in the opposite direction from the tower and receiving the powerful signal being collected by and reflected from the large pine tree in the neighbor’s yard. |

Originally posted by coyotefred A couple of folks have suggested the reflector idea elsewhere, and that is a real creative idea... I assume you could paint the thing too so it does a better job of blending in. It may be that I can simply point the yagi at the hillside itself (or some feature like a rock outcrop on it). coyotefred |

Originally posted by sid pearlman . . . Why not make a reflector? A sheet of plywood coated with some (aluminized?) paint... tinted green or paint with camo, to blend in. . . . |

Originally posted by Life-Is-Good I finally figured out that the main “boomer” tower for this part of Santa Cruz County was on a hill a quarter mile away and that tree was just reflecting the extra powerful signal from the boomer :laughs: |

Originally posted by sid pearlman "Common sense" would indicate the opposite. . . . Do you aim the yagi any where off a horizontal axis...meaning up or down? - Sid |

Originally posted by Life-Is-Good Having designed quite a few antennas I can’t imagine a plywood reflector like you have described working at all, but anything is possible. |

Originally posted by sid pearlman Lots of plywood? After all... it's just a flat tree ![]() Thanks, Sid |

Originally posted by coyotefred I have plenty of trees at my location...I'm anxious to try a couple of them out! . . . |

Originally posted by coyotefred . . .where did you get your yagi? How big is it? I was trying to decide whether it made sense to get a larger yagi (e.g. 60"), but a poster on another forum says that a 60" yagi would only give you about 14dB gain, only 3dB more than a 24" one... |

Originally posted by xan_user Wilson's cable chart states 4.0db loss per 100' w/9913 cable (13/32") compared to 1.2 db loss per 10' w/ RG 58 (3/16") OE- Does heliax cable work better than wilson's? or is that a 4 db loss per 100' as well? |
| That's for the whole 200'. Heliax type* coax is what is used for permanent installations. As a rule of thumb, we'll tolerate 3 dB of coax loss (including connectors) at MOST. If it's going to be more than that, we bump up to the next bigger size to get the losses down to an acceptable level. When you are talking about a minimum of 6 cables running up a tower (or across a rooftop) at those kind of prices, you can see that the bean counters don't like us to use the biggest available. We use the smallest possible consistent with maintaining the required signal level. |
| (All losses here are at 850 MHz. Losses at 1900 MHz will be worse.) |
|
Originally posted by OldEngineer That depends on the length and the cable. At 200' with RG-58, it's over 20 dB. Switch to RG-8 and it's ~9 dB. With the Heliax mentioned above, it's only ~1.5 dB. Here, see for yourself: http://www.ocarc.ca/coax.htm |

Originally posted by OldEngineer . . . How far you can send it depends on something called a link budget. That's basically a calculation of how much signal you can afford to lose before your communications degrade below an acceptable level. It takes into account things like transmitter power, receiver sensitivity, path loss (the signal loss through air), cable losses, and antenna gains. If these gains and losses are all expressed in dB, you just add them up. . . |

Originally posted by xan_user Thanks for the info OldE !! A couple of friends have asked if I could help them get cell signal to their 'remote cabins'. One guy is in the bottom of a deep canyon, maybe around 1500 - 2000' in distance from a usabe signal on the ridge. I'll see if I can get another yagi and give it a try! Is there a company you'd recomend? I know your not fond of Wilson.
|
| Info like this comes free with project proposals. Then you get charged $300 per hour for guys like OldEngineer and me to actually make it work, heeheehee. |
| You're going to need a repeater for that. |
| If your're trying to recieve a 1900 MHz network, use a dish antennas for best results. |
| As for a brand.... Try anything BUT Wilson or Larsen! |
