LNA power supply?

Re: Who has a Discone in the Attic?

Thanks for the tip. I'm also thinking about not using the whip antenna on the top so I can get it up higher. I'm not sure around here anybody uses that frequency which I think is around 30-50mhz. Maybe baby monitors?

Re: RG6 or RG8?

I just found some Perfect Vision E341555 RG6,but I believe its Copper Clad Steel. Would this work for the short run or should I stick to solid copper?

Who has a Discone in the Attic?

After trying for a few days,I have lost the battle to put the Discone on the roof. I know that I would get better coverage on the roof,but having an antenna that sticks 10-15 foot higher than the actual roof isn't going to cut it.

RG6 or RG8?

Since I will only be listening to my local Trunked P25 system and not transmitting, will RG6 enough? My run will only be around 25-30 feet from the discone and the laptop. Is 50 or 75 ohm going to make a difference?
