Neither aluminum window frames nor 23rd floor plumbing pipes (which usually turn to plastic once in the framework of the building) will suffice as a substitute for a good earth ground... Does your radio require an "earth ground"? If so, try a tuned counterpoise on the ground lug for the bands most listened to... It will probably do the trick (If you need help locating one let me know via email, I have an extra one). BTW - your email bounces. Best of luck. John "Lucky" wrote in message ... Hi guys! I live on the 23rd floor of a building so I can't use the earth directly for the ground. The options in my "radio room" are the ground from the electrical sockets and that's about it. I've heard I can roll out 10ft of tin foil on the floor as a ground {that's out}, or, use the window frames as a good ground. As far as I can tell, the window frame looks to be aluminum or some sort of alloy. Have any of you heard of using a window frame as a ground? I think I read it in this NG that someone recommended it and was using it for his ground. I've been using the ground from an electrical outlet. But being that so many people live in the building that use appliances and other plugged in items all day and night, I sometimes get what seems like bad feedback affecting the receiver. So what do you think of the window frame for the ground then? I welcome any other options I can use in a room very far from a direct earth ground. The bathroom pipes are all the way across the room separated by a wall. Not easy to get to. Thanks for any help Lucky Hi guys, Yes I didn't tell you what antenna I've been using. BTW I'm not transmitting at all, just receiving.Due to size restrictions I have one random wire about 30 Ft long and a dipole approx 16 ft total length connected to a 4:1 current balun. These antennas are on the outside terrace and are fed in thru a window. I had another smaller dipole like 6Ft total connected to the same balun also but have since taken it down. The seller of the current balun told me I didn't need a ground for it. I didn't know much about dipoles then. But that I should still ground the radio itself. The seller was RFjunkie from Ebay. He seemed to know a lot about them so I grounded the R75, Lowe HF-150 and all of my radios since then. He said I would need a ground if it was a Voltage balun though but still ground the rigs using the current balun just to be sure it I wanted. Now, in all the radio manuals I read, and from reading many sites, they all claim one must be grounded and grounded well even if receiving. I think more of the old time users were adamant about grounding your radio for proper use and protection. I read about static building up and the radio having to have some kind of grounding. So I grounded and many times it seemed to lower the noise floor on some frequencies. So how do you know if you're making a real ground or just another leg of an antenna?? Thank you kindly for all the replies My e-mail bounces due to all the spam when I have my real one up. Lucky |
