Will I lose much signal using 100 feet of good shielded 58U - CB coax for my 25-800 MHZ scanner receiver (compared to 25 feet) ?

I am currently using 75 ft of cable and reception is as good as I expect. The height of actual antenna makes the most difference in reception. Mount it as high as possible.
1190771
Yes you will. At 200 MHz you loose 7.3 db. At 700 MHz you loose 17 db. For every 6 db in loss you reduce your reception range by a factor of 2.

You signal loss between 25 ft and 100 ft of RG58U, but you would be much better off using a good grade of RG6.

If you are using RG59 cable you should keep the distance at or less than 750 feet. Over 750 feet you should switch to an RG6 low loss coaxial cable. IF you plan to bury the cable, ensure that the coax is rated for burial. The real issue is with the power. 700 feet over the small gauge conductor may be an issue, depending on the wire size/quality. Use a voltage drop calculator to determine wire size and input voltage. If using the Qsee brand cable provided with the system, i would say very unlikely to support that distance.

Yes it would. As far as tx distance not sure. But should be able to rx without a problem. I haven't upgraded antennas but I just use as a local handheld scanner anyway.

I had nothing but trouble with 2 of those amplifier. To get stations 70 and 20 miles away I put outside antennas with a pre amp plus a rotor to fine tune reception. If your stations are close, you will still need at least a small outdoor antenna. HD stations need good signal reception.

A great question, unfortunately the answer has to be "Maybe...". There are a lot of fancy technical factors that influence what you can receive and the quality level of the signal. 75 miles is a long way for VHF/UHF signals but the proper antenna at a good height may work. The good news is there's a great resource on the internet at http://antennaweb.org The site will help you determine what type of antenna you need in your specific area. Regarding this particular little antenna, my educated guess (I'm an engineer) is that it may pull in some of the distant stations if they are strong enough, and if you can get the antenna as high in the house as possible. These little antennas can actually be placed in an attic and a cable fed to lower level TVs, if you're willing to go through all that. Bottom line (finally...): The thing is so cheap you can try it and return it if it doesn't do the job. Hope this helps you out.

I don't believe the antenna will work 100 miles. The range is approximately 25 to 30 miles for a good signal. I can say that with confidence as I'm that distance from the TV towers... I am able to pull in 25 channels with the Ghost Antenna... I'm very happy with it and purchased (2) more for my brother-in-law and sister-in-law. They are in the Boston area and get 36 channels.

Probably has, why not? Coax is just an RF pipe. I'm using it for 0 - 30 mHz receive only.

I would not recommend going wireless for this distance with all that metal in the line of sight. Tried on shorter rig and kept losing the signal.

Yes. Just turn up the squelch to drown out the static and hit scan. It can pick up signal from quite far out.

A 69 Dollar discone off Amazon will do nicely. Get it up 40 feet and you're set. Use a 50 foot run of RG8X coax or if you have money RG213. Don't forget the correct coax ends to match the radio and the antenna. Do NOT use adapters!

75' is a real push but I had a much older unit work at close to 100' with the RF, the problem the newer units have are usually with the IR signal alingment

I am 30 miles away from broadcast towers and although they are quite clear, the lower channels are tough to tune in. I'd say you should probably go with a larger outdoor antenna at that distance.

Any standard coax cable should work fine. Don't know if that will affect reception. Probably depends on the total length.

You could if you know how to attach a new PL259 coax connector...that is problem one...problem two is that sometimes the length of the cable is actually part of the antenna design so it may not work quite as well...my suggestion is to just roll it up neatly and tape or tie tag it...

100 miles is really stretching it. It's going to depend on terrain, height of antenna, do you use a pre-amp? And transmitter strength of the station. Use the internet to research this antenna.

clearwire is 2.5 ghz which this antenna covers, however, you will need very high quality coax or very short coax runs to get the signal from the antenna to your reciever. LMR400 or equivalent and N type connectors are needed and this coax is about as thick as your index finger. Line loss with inferior coax is horrendous at these frequencies.

I can say it will do it, but you could hook up an external antenna to the back, which would definitely help. I bought one for my Mom, who lives about 75 miles from New York City, and it worked o.k. for her, but on a powerful station, WCBS. You could also look into getting an antenna booster system. C. Crane sells a "Twin Ferrite AM Antenna system. The way it works is that you mount a Ferrite antenna outdoors, somewhere where you can get a good signal, like up high, not near any obstructions, etc. A coaxial wire brings that signal into the house [you need to make a small hole], and then there is a receiver sections that you can tune to the one station that you want to receive, and the receiver has an antenna that rebroadcasts the signal from that station amplified. I looked into hooking that system up to get some weak AM stations, but haven't gotten around to it yet. The reviews for it are very encouraging. Living in the mountains might make getting your stations difficult, and also it depends on whether you listen day or night. Usually the signals travel longer at night, but the stations also cut back on their power in order not to interfere with each other. I am sorry that I can't give you a definite answer. One thought is, if there is a Ham Radio club in the area, try connecting with them. They usually have a good idea. Last thought is internet radio or Satellite radio like Serius. That is what my kids finally did when they couldn't get the AM and FM stations they wanted, even though it costs them.
