Donna and I did a two nighter at our local 40 minute away Hoosier National Forest. One of the sites we prefer is down in a low area and we can only get 1 and sometimes 2 t.v. channels ( I like to catch news and wx ) So I used my limited knowledge of Electronics and Signal propagation learned when I got my F.C.C. Radio Telephone 2nd class license a hundred years ago. I took two pieces of 1 ft square aluminum foil and put double sided tape around the edges and stuck them to the ceiling of the pod on the inside directly below the amplified antenna. On a Rp-172 this is where the upper cabinets are. One side is inside the cabinet and the piece to the right is exposed above the netted storage area. This is basically a passive improvement of the non exsisting ground plane below the antenna. Whammo , I went from 2 channels to 10, I know this is not a fluke as we have used this site on and off for 4 years and never got more than 2 stations at night and sometimes none in the day when signal propagation is different and the power is reduced. Give it a try its cheap. I guess you could use colored foil if you don't like silver.

You increased the size and effectiveness for the ground plane of the antenna!  Next thing you'll be tuning in Rangoon!

Q-7, I thought about running a small 16 gauge wire to the common in the pod and then to both of the pieces of foil to really increase the ground plane , but it worked so well I thought leave it alone. You are right about increasing the ground plane therefore increasing the signal strength, I bet I got 9db or better gain. I kind of found this by accident as one time we were watching the weather and it kept fading, I took a roll of foil and moved it around under the antenna and tried different positions and it would help if located in the right spot, trial and error.

Sweet.  Next step would be to string a cheap outdoor television antenna 20 feet up in a tree.  Or replace the pod's antenna with a Yagi.
