Few dumb questions:
1. What sort of 5G filter would you use?
2. Other than something like ASC1, how would you control polarity? Any way to do this with a Vbox?
3. After a lot of time/money, how much performance gain over C2PLL?

I happen to notice that the C2PLL is currently not listed on Titanium store. Is it just out of stock or is a new model on horizon?

1. If you need a filter, use an inline waveguide filter cut for the desired band pass or cut and/or a filtered LNB.
2. The servo motor is controlled via PCM. One could build a PCM servo controller or use a legacy IRD. The v-box could provide the power for your PCM controller project board. :D
3. The servo adds the ability to remotely fine tune the polarity skew to optimize the target signal and /or attenuate interfering signals.

The C1PLL and C2PLL models are now out of production. In a few months we will introduce the new BPF models to address the potential interference from the 5G services >3.82GHz. The first models released will be band pass filtered for 3.82 - 4.2GHz pass-through to address interference below 3.8GHz and next year the 2nd models will be 4.0 - 4.2GHz pass-through to address the future 2nd C-band spectrum action.

Have you experimented with the new narrowed band LNBFs? Current performance with my C2 is great, but with a new design covering a narrowed band, I was wondering if there is any noticeable improvement in performance specs? I am a HAM and was always told the narrower the band you are trying to receive, the better performance can be seen (in terms of a broadband vs band specific antenna).

How do new models compare to C2PLL?

Like anything I develop or resell... if I wouldn't use the product on my own personal system, I won't sell it. Wouldn't discontinue extremely popular products if the replacements weren't better and fit the evolution of the market. :)

The C1 and C2 models were developed to meet the filtering requirements in use at that time. These legacy models will no longer have the appropriate band pass range for filtering the new band plans in the staggered roll-out.

Uh oh maybe I shoulda waited a few more weeks when I bought that C2 lol

Also <Jerry Seinfeld voice> What’s the deal with HAMs and FTA satellite? I got my General and a BUD this year. I guess they’re both radio hobbies that go together hehe.....

I'm currently using a C2PLL and not aware of 5G interference although guessing I'll upgrade when the new model comes out.

None of us in North America have any need for the tighter 3.8 - 4.2GHz or 4.0-4.2GHz BPF (Band Pass Filter)... yet. In just over six months from now, we will start to learn who will be affected and how strong the interference WILL be or will become. Some systems will need nothing, others will mitigate the interference with BPF LNBFs, others will require mechanical filtration and/or LNB BPF and others will need to physically move or shield their dishes.

You have what you need... for now. :cool:

Not to get too off subject, but I did see a fellow dish hobbyist from Mexico build a TI Faraday shield with a little bit of screen mesh for his buttonhook feed. This could be rigged for a traditional 3 or 4 leg support feed assembly too.

Interesting. Not where I would install a RF shield Seems that it is only compensating for an incorrect FD placement and over- illumination of the reflector. Glad it worked for his system and specific angle of the interferring signal. Likely will not apply to most other installs.

My bet is that we are going to see many "solutions" over the next few years.

That would work better, but he's got it lined up so the opening of his feedhorn cannot "see" beyond his dish rim. I guess if it works, that is fine for him?
IF the scalar was installed at the proper distance from the center of his dish, it wouldn't see beyond the dish rim anyway. No need to cobble it, if it's done right in the first place.
