Re: C-band affected by weather
C-band satellite television reception is impervious to overcast or rain/snow conditions, unlike it's little cousin, the ku-band dish. This is why the industry settled on this band of the electromagnetic spectrum for national distribution of television programming in the 1970's. However, due to the rather large size of the typical C-band dish, high winds can cause issues if the installation is not done properly.
If you are installing a new C-band dish and doing an in-ground post installation, make sure you use a post with welded tabs at the bottom to avoid having the post rotate under extremely high wind loads. Also, make sure you tighten down all the nuts and bolts and check for slop once you got the dish mounted on the post. This will go a long way in avoiding performance issues under extreme weather conditions.

Re: C-band affected by weather
Oh yeah it is. Certainly not as much as ku band reception. A few dB.
Your biggest problem is snow on the dish. Silicone spray and Rain-X on the dish will help. A broom is better. You need exercise anyway.
Not impervious, just resistant. And if motorized, don't leave it up in the sky during a blizzard. Common sense.

No, not even close. Next time it is pouring, check your signal levels.supwiddiss wrote: ↑Wed Feb 13, 2019 3:14 pmOh yeah it is. Certainly not as much as ku band reception. A few dB
Signal attenuation due to rain fade is directly proportional to frequency (and likely raised to some exponent of the frequency). Thus, little or no attenuation (less than 1 dB) in the c-band, some attenuation in the ku-band (5 - 10 dB) and massive attenuation in the ka-band (complete signal loss). Just ask Direct TV customers in Florida about the latter.

Re: C-band affected by weather
Yes. To say impervious is misleading. For example on 131W when there was a blizzard the other day I lost 3-5dB signal.
Went out and swept the dish off and gained a dB. Looked up to 50W and signal was close to what it should be.
Head ends and news broadcasters have huge dishes. Go figure.

Re: C-band affected by weather
Heavy snow sitting on your dish will cause the parabolic shape of the reflector to distort slightly. This was likely the cause of your signal loss. To minimize snow accumulation, if at all possible, drive your dish to the lowest horizon satellite. C band for the most part does not suffer from rain fade like the little dishes. This is a well known fact.supwiddiss wrote: ↑Fri Feb 15, 2019 1:00 pmYes. To say impervious is misleading. For example on 131W when there was a blizzard the other day I lost 3-5dB signal.
