I'm a newbie, and don't have a dedicated spot for my radio yet. I have been setting up my end fed 10/20/40m dipole, putting the radio on the living room desk, and running 25' coax through the window to the antenna when I want to listen. I tear it all down when I'm done. I know the radio chassis should be grounded (in addition to the 3rd prong on the power cord) and there's a lug on the back for it, but I'm not sure how / where to ground it since my living room desk is all the way around the house from the electrical service ground point. I am not at risk of lightning because I would tear it all down if a storm came through, but I am getting ready to try transmitting for the first time and I thought maybe I should get it grounded for that? I'm limited to transmitting 25W by the antenna, but I don't think the transmit power matters, it should still be grounded, right? I am concerned that pounding a ground rod in near the transceiver is a bad idea, as I should probably tie to the common house ground point if I'm going to ground it at all? Any thoughts are welcome. On a side note, do you think it'd be smart to use a choke at the end of the feed line to avoid the coax ending up radiating? If I did that, would I still need to ground the chassis of the transceiver?
