Pete Higgins has posted a review of the TVPRAMP1R:

I have no reviews to refer you to, but the Winegard LNA-200 specs are impressive.
If you need a 10 foot mast, consider a section of chain-link fence top rail. It's one gauge number thicker than the CM-18XX product. I find it at Home Depot locally. And it has a swedged end so you can stack it if needed.

I use
Scotch #2228 sealing tape. Coax Seal is another brand name to look for. In either case you simply stretch it snugly as you wrap a connection to be sealed. Both products are tacky, so I wrap black electrical tape over the sealing tape to protect it from UV rays and dirt. Common electrical tape will not seal against moisture by itself.
