If you have one of those antenna and want to press it into service, that's one thing.
If you are going to buy one and use it for FTA, I think that'd be regarded as a bad idea, based on those prices.
I'm referring to International or GainMaster models, only.
The GainMaster would need a new LNB.
The International appears to have one linear LNB with it.
But for $150, there are probably much better combinations.
