Stupid dtv is being a serious pain. There is a problem with one specific station, where sometimes it works, sometimes I get nothing unless I hold onto the coax cable. All the other channels are fine, and the problem one is the closest, just under 5mi away.
Currently using a medium sized antenna outside on a 10ft pole. The cable goes in through the side to a coax wall plate, then to a converter box.
I don't know what the problem is, if it just that it needs to be higher up or if there is a grounding issue. What exactly would need to be grounded and how is what I am stumped on.

Whats the best antenna rotator?

I've never used one, but the better choice is probably a different style antenna meant for signals in different directions

Have you tried aluminum foil?

as dumb as it sounds....yes

this is where 'grounding' gets fun, and why you shouldn't use ground for everything.
the shield of the coax is just the second wire to the antenna, the signals it collects and sends down the cable need two wires to create a current loop just like everything else.
the reason its connected to a local electrical ground is because ground is good at collecting wayward voltages and stamping out signals picked up by the braid to stop them hitting the signal core in the coax. gives them somewhere to go. but its not perfect.
so lots of things could be happening. you could be giving the shield a better ground because of your capacitance or you could be picking up the tv signal and imposing it on the coax. the signal might be too strong and you are adding noise omto the ground effectively reducing the signal to a reasonable level.
whats the converter box? outside? full of water?
normally i would say rip it all out, scrap wall plates, log periodic aerial, new foil shield coax. then work in any wall plates, splitters, if you want and see how it affects signal.

what is it?
>A digital television adapter (DTA), commonly known as a converter box, is a television tuner that receives a digital television (DTV) transmission, and converts the digital signal into an analog signal that can be received and displayed on an analog television set.
no it is not outside, they're never meant to be used outside

look up the specs on the station, frequency and transmission power
VHF channels still exist, but had to dramatically lower their power.
VHF frequencies also tend to require a different style antenna or second feed.
See if your antenna is tuned primarily for UHF and lacking VHF elements
or just use some old bunny ears and a loop

it looks like this one

yeah, I'm thinking the station might be partly at fault since it seems I'm not the only one with a problem with mainly this channel
I will look for one of those junky flat antennas just for kicks....maybe see if I could get it somewhere higher up

OP
people sometimes are very surprised to note that a cable fitting has A LOT to do with the reception you're getting. make sure your fittings are flush with the dielectric (white stuff inside coax) and that they're screwed on TIGHTLY at every connection (including BEHIND your wallplate).

that is for high vhf, but not low vhf
i put this in my attic and i pick up all the channels
