in my 46-1226 cabinet i have a box antenna that gets good to decent AM reception and nearly nothing on SW while in the house.
SW comes and goes but the hits across the dial are maybe one or two and very low amplitude.

while the radio chassis was under restoration in my garage, i had the ability to use my 500 or so feet at 70feet height random wire so AM and SW were great.  many stations were coming in especially on SW.

Part 1 question:
I am looking for a way to improve on the original antenna design such as buy something already to go or make something.   Id like to make something to be honest this way i can control its looks to blend to the era of this 1946 model.

Part 2 question:
Is there an aftermarket solution that i could hide in the radio somewhere that "pre" amplifies a radio signal?  thsi way i would use the output of this device to feed my  antenna input?

home construction is 10'' log two story home with metal roof.
I have a balcony off my bedroom thats about 10' x 40' and its screened in.  My tinkering mind is hatching an idea that i run an outside random wire to the screen, then jumper the screen to my metal roof. the screen is not grounded yet is attached to the red oak two story balcony i made. I know i should have my roof grounded but its not.
years ago i used the roof on this radio and it worked great but,, i would like to be able to relocate the radio around the house if the wife chages things so the random wire forces the location of where the radio is in the house. 

is there a superior new tech solution to this problem that i can blend into this radio?
