Planning to have my two story home re-roofedwith asphalt-fiberglass shingles.  Question is... is it a good idea to prepare for mounting an antenna and an attic pass-through installed at this time in preparation for an undecided type of antenns? Still deciding on antenna for Ten Tec jupiter radio. Just returning to Ham radio, is it wise to get antenna above my capabilities or start simple?

Thank you for response. Some added information..as of now I hold a Tech Plus license obtain some years ago, however because of an illness, never pursued the oppurtunityto learn Amateur Radio hobby. Now after 6 years of kidney Dialysis and a successful Kidney transplant...I have the time and desirse to pursue that hobby. The room I intend to turn into a shack is the one that I had used for the home dialysis. It has a dedicated wiring and water pipes which I was hoping would benefit the shack requirement. If it fulfils grounding requirements. It's a two story home and I was hoping to attach an antenna on the roof or chimmney and route the feedline through the attic ceiling (or through the wall)?. Right now I am preparing for a General License up grade and would like to operate CWand DX. I have not purchased any equipment as of yet and I am leaning toward the Ten Tec Jupiter, all equipment selection is up in the air. I am also checking the available clubs in the area. Thank you

Beginner wants to know!  Planning to set up radio shack in vacant 2nd floor bedroom. What problems
should I expect?  Room already has separate 30 amp outlet and access to a cold water pipe . ( for grounding??) Lots of room on roof for antenna(s).  Also, handicap prevents my working on roof and other limitations. Are there professional companies (particular with Amateur Radio knowledge) that provide installion services. Please excuse these basic questions. Thank you
