You should get out more. Never heard of a "potable antenna?" Amazing.
Yes, it is an old one all right, but as it turns out I have started to deal with this issue in the past couple of days. Here is where I am at the moment: I had made a clothes hanger antenna a while ago and tested it, found it to be very good when connected to my basement monitor/TV. Turns out it wasn't needed since I discovered that my son had left a second antenna installed on the roof before he moved out (geek). I considered one of those "boomerang" deals, but the price is pretty high. I have one of the Winegard Sensar antennas on the trailer and have struggled with it to little effect. So I dragged out my 26" double-duty Samsung from my computer setup, plugged it in to the Winegard, got nothing until I turned on the amplifier and rotated the antenna to best effect. Two channels out of many and quite iffy at that. (The location is not so good, with some trees and buildings compromising the signal path.
So, I hooked up the clothes hanger thingy, laid it on the counter, and EVERYTHING came in as clear as a bell. That got my attention. I have decided to remake the antenna, using 1/2" wide anodized aluminum stock instead of the clothes hangers, mount them on 3/8" thick acrylic and fasten them with S.S. machine screws.
The plan is to locate/store the antenna on the inside of the rear gravel guard but to make it so that it can quickly be put on a pole to elevate it and mount it near the opening of the rear window so I can just reach out to rotate it while watching "The Bachelorette" or something. I have already tried the old one in that position and it works very well. When I have made it, mounted it, and tested it I will document it here with prose and pictures for all to see.
It has been one of my fondest dreams to ditch that heavy, ugly, ineffectual, air-flow-resistant Winegard monster. Now that looks doable to me, so the only thing left is to upgrade that Samsung, which is much too small.
