I am 2 months new to scanner receiver radios. I wanted to monitor local air traffic at DIA (about 18 miles away), Front Range Airport, (about 16 miles away) Buckley Airbase (about 5 miles away) and Centennial Airport (about 10 miles away.) I also wanted to receive CB, MURS and FRS bands.
I knew I would have an uphill battle with my shop in the basement. Even though Aurora, Colorado appears very flat, our home is in quite a gully. My first mistake was not reading more about frequency use. I purchased a BC355N that I am happy with but then soon realized the military air frequencies could not be covered. I then purchased a BC125AT and now have coverage of all the frequencies I am currently interested in. I realized soon into research that police or fire monitoring would be difficult in this area due to our departments using various higher end and encrypted equipment. Even if I went up the food chain and bought a BCD436HP or a TRX-1 I do not believe I could even monitor theoi communications yet so the BC125AT is all I seem to need for now with the BC355N covering everything except military air.
When I drive up out of our neighborhood to the "normal" street level, I get good reception even with the stock antenna on either of these scanners. (The BC355N has a telescoping metal whip and the BC1q25AT a rubber duck.) In the shop, much less traffic is received. I bought a discone and placed it in the attic like our TV antenna is. Perhaps there is a cold solder joint on the cable end or the fact that our south attic wall (just one wall) has a foil liner, regardless, I get no (I mean zero) reception from that cable that took me three hours to run down into the basement shop. One post here was correct that predicted that result. I still went ahead with it all because so many others yet had reported such great success with discones for receiving a wide range of frequencies.
My next move will be to move the same discone antenna onto a pole atop the back deck that will allow the bottoms of the "umbrella" part to be about 2 ft above the gutters on the top roof of the house. I will check the cable better to be SURE it is not cold soldered or otherwise bad.
MY QUESTION is, if this discone still does not help once remounted outdoors and away from that one foil covered attic wall, what do you experienced guys think the result would be if I just put a regular whip antenna (like a 14" rubber duck replacement antenna) on a PVC pipe up there above the gutters with a good coax cable coming down to the scanner in the basement? Do you think is would just be a waste of time?
One other thing I considered is the "car antenna" the BC355N came with. It looks like a stranded copper wire perhaps 18" long with two suction cups you place on the windshield. When I use it it is an improvement over the BC355N whip antenna when I use it in the car. Maybe I can fashion something as simple as that vertically along the side of the house up on the outside wall of the second floor. I have Masonite siding on the home. Does anyone think that could make a significant (hoping for 3x) improvement over using the standard whip antenna on the back of the scanner in the basement?
Again, I want to receive the wide range of frequencies on my scanner that I mentioned above but not transmit. Any recommendations for better scanner reception over a wide frequency range will be welcomed.v (I realize my question sounds like "Scanner Antenna 101" to most experienced guys.)
