1) any quality difference between BNC and F-Type?
2) Does a BNC to F adapter cause quality loss?
3) People love Monoprice, what about Deepsurplus (Deepsurplus is cheaper)?
4) Splitting antenna cable, is a splitter enough or do you need this here? http://www.deepsurplus.com/4-Way-Coax-Signal-Amplifier-Chrome-Plated-with-Gold-Fittingbrfont-colorblackAs-low-as-2-55?sc=2&category=82398
5) when you snap this http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10426&cs_id=1042604&p_id=2873&seq=1&format=2 into this http://www.monoprice.com/products/product.asp?c_id=105&cp_id=10517&cs_id=1051703&p_id=1097&seq=1&format=2 , is it recessed or does it look out of the wall?

1) Why would you want to use BNC?
2) Probably not noticeable.
3) People love monoprice for their interconnect prices, hard to beat them for HDMI and DVI cables. Never heard of deepsurplus personally, if they have good prices on the particular things I need and good online ratings I'd use them though.
4) Depends on your signal strength to begin with and how many splits you need.
5) They appear to be flush, the first picture looks like the backside of the connector, click enlarge then the other picture.

thanks ,

well, I don't know the difference between BNC and F.
Looking at it my question really is if BNC is the same but just snap in and F is screwing on or if there is any other difference?

here is the amp, is that any good for that price?

I'm gonna guess that amp is not all that good for the price and no brand name markings on it.

Looking at it my question really is if BNC is the same but just snap in and F is screwing on or if there is any other difference?BNC and F type connectors are both coaxial connectors but are very different and NOT interchangable. F type is threaded and generally used on consumer products, while BNC is a twist connector and used on professional products.
