If you use the TII 212, it has a screw terminal for a grounding wire, so it can combine both functions as a grounding block and a surge protector. You will not need both devices.

If you must use a coax surge protector instead of a grounding block, the TII 212 device before entry is superior to the coax surge protector in a power strip. It provides protection before entry AND it avoids interference pick up by the coax when connected to a power strip.

The NEC requirement is for two grounding connections to the house electrical system ground, one for the coax shield and one for the antenna mast.

Since I have had three close calls with electrical shock, I consider grounding the coax shield of primary importance. The coax is connected to AC operated equipment, some of which does not have a 3-wire power plug. If the equipment malfunctions, the coax can have a dangerous voltage on it. Even properly operating equipment has leakage current. Case history:

The grounding wire for the mast is to drain any buildup of static charge to discourage a strike. The code says if there is a separate grounding rod for the mast it should be bonded with the house electrical ground system with 6 gauge copper wire (very expensive). Your case, with the mast in the ground already is in the gray area, and needs to be treated like a ham antenna tower.

If you can not measure it, you can not improve it.

As I live in FL, and the Tampa Bay area is one of the world's hotspots for lightning(no not just a Hockey Team), I feel that I will need all of the protection that I can get. Unfortunately, disconnecting every time there is a lightning storm is not practical.



Back to the gain booster...


Based off of my location, it may not be needed. However, I am planning on splitting the signal into three lines(TV, PVR, and DVDR). As mentioned earlier, there may be some signal loss after the split. Also, if I run the line through a surge protector(for additional protection-being in FL and all), I assume there would be additional signal loss.

Grounding the coax and antenna mast provides a path to ground for static discharge and gives your system some protection. If you take a direct hit then everything will blow up. The only way to protect against that is to disconnect the antenna during a lightning storm. Fortunately direct hits are not common. It's the induced charges from nearby strikes that take out most equipment.

Your signals are strong to extremely strong, <30 miles away and in the same direction. You do not need a preamp and probably not a distribution amp either. If you are splitting 8 ways then a CM-3418 would be in order.

I'd recommend a Winegard HD7694P antenna.

I'd agree with the separate FM antenna idea. Currently I don't have my FM antenna in the air. I have a low VHF antenna occupying that spot on the mast. It can used used for FM on stations with decent signals.

Interesting. When WTVT has to put up a weather graphic over network, the whole thing skips ahead by 2 seconds. When they go back direct to net, they go back 2 seconds and we see the same video/audio over, again. Took them a while to do it, too. Kept hearing the beeps, but then nothing on the screen.

Also, it seems to me the audio level on network direct is lower then when they're routing it through a switcher. I'm guessing whomever is working the game is having fits getting a weather graphic up. He/she got the crawl going, but that's it. I'm happy, too, as they're putting the graphic in the 4:3 area. Blocks a lot of the game.
