A black helicopter has them hiding under the > bed. ;-) You must live in my neighborhood! :) You bring up two important issues: a. Power at the remote site 800 feet away, and, b. The Fresnel zone of a pole only six feet tall You can look up the Fresnel zone stuff separately, which, in my experience, is more theoretical than practical since you just shove more directional beam power to overcome the losses due to lack of height. Power is an issue. I'll ping "alt.internet.wireless" & "sci.electronics.repair" with this post, who may be able to assist you more so than I can in how to set up the power (be advised to ignore the three infants on s.e.r if they respond). What we do here in the Santa Cruz mountains, where the zoning is 40 acres per household, is "bucket routers" which are simply routers plugged into anything we can plug them into, between homes when we need to clear obstructions to our Line of Sight (LOS) WiFi transceivers. But your suggestion of solar seems far better than bucket routers. -- A "bucket router" is just a router under a bucket for weather protection. |

Passive repeaters like that don't work. For example, let's take an over simplified situation. This is for a direct path (no repeater) between the TV station and the receiving antenna. UHF 14 channel at 500 MHz. 10 mile path. 12 dBi antenna gain on the receiver end. <https://www.proxim.com/en/products/knowledge-center/calculations/calculations-free-space-loss> The 10 mile path produces a 110.6 dB path loss at 500 MHz. Add the 12 dBi antenna gain and the station to receiver path loss is: 110.6 - 12 = 98.6 dB loss Next is with a passive repeater installed at 9 miles from the TV station and 1 mile to the receive antenna. At the 9 mile point, there are two back to back 12dBi UHF antennas. This splits the calculation into two parts (9 miles and 1 mile). Note that there are three 12dBi antennas involved: The 9 mile path has a loss of 109.7 dB. The first 12dBi antenna reduces the 9 mile loss to: 109.7 - 12 = 97.7 dB loss The 1 mile path has a loss of 90.6 dB. The 2nd and 3rd 12dBi antennas reduce the 1 mile loss to: 90.6 - 12 -12 = 66.6 dB loss The total end to end loss (including the three 12dBi antennas) is: 97.7dB + 66.6dB = 164.3 dB path loss 164dB is a *MUCH* larger path loss than the original direct path of 98.6dB even though it includes the gain from 3 antennas (+36dB). Specifically, the direct path signal through such a passive repeater arrangement would be: 164.3 - 98.6 = 65.7dB or about 4 million times stronger (in terms of power gain) than the passive repeater derangement. This is why you don't see many passive repeaters, passive cell phone boosters, or flat panel reflectors, in service. >house with literally an aluminium coat hanger plugged into the >antenna socket. By contrast, I could watch the 1990 FIFA World >Cup only with an array of four yagis *and* an antenna booster. 1990 was before repacking and DTV (about 2009), so that wouldn't explain the signal loss. What seems odd is your "slowly but steadily degraded". That seems like some kind of TV receiver problem, mechanical problem (squirrel chewing coax, water in the coax, antenna rot), that gets worse over time, rather than a sudden change. Were the neighbors experiencing the same problem with the same station? Are you on a shared community or building distribution system? Were you listening directly to the unspecified TV transmitter, or were you listening to a station owned UHF repeater? -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
