Is it possible to lay a cable from a GSM antenna in a metal corrugation?

Question

Antenna

I plan to amplify the GSM / 3G signal in the basement, dragging the cable around the house to the external antenna is long and difficult, I decided to run the cable from the basement directly to the street and further along the facade to the roof. Since the cable will come out very low and close to the ground, there is a chance that my bad dog will gnaw on the cable. As an option to run a cable in a metal corrugation - will it affect the quality and signal level?
I will use an 8D-FB cable (copper) of only 20 meters, I will lay somewhere 4 meters in the corrugation. Vegatel VT-1800 / 3G repeater

Answer 1

Not being a professional, I’ll try to answer: you can lay it, your corrugation will shield the cable from external interference. Here are just:
1) Is there any certainty that the dog will not gnaw on the corrugation?
2) If you lift the corrugation high, can it become an excellent lightning rod?
3) If water gets into it in autumn and it freezes in winter, will the corrugation withstand such tests?

Answer 2

Being a professional in this matter, I will try to answer:
1. It is best to use a metal hose in PVC insulation http://www.etm.ru/cat/products.html?val=Metal hose... It is protected from atmospheric precipitation and does not collapse in the sun .
2. Fasten with metal brackets for the corrugation.
3. A metal hose or pipe will not affect the quality of the signal in any way, it will even protect against interference from power circuits.
4. Ideally, the metal hose is grounded to the ground bus in the switchboard, in practice there is not much point in this.
5. From a dog, a rise of 2 meters can be protected by any pipe of a larger diameter than a metal hose.
P.S. The repeater is only in the 1800 MHz band, are you sure that it will be enough for the existing network? You can contact me at www.konbez.comor here.
