I’m in an HOA searching desperately for a solution I can leave up (currently putting a 33 foot military mast up on the weekends w/ a G5RV). I’ve got about 53 feet between two trees. Was wondering if I could run this up the tree and over to the to the tree 53 feet away in an inverted L configuration and get good results or not?April 30, 2015 at 6:28 pm #963QRPMEParticipant
Could you give us a little more information on the deployment?
It sounds like you would be better off running the QUAD as a sloper. It is 65 feet long if you are operating at the bottom of each CW sub band. If you mostly operate in the phone portion then it will be somewhat shorter. The 10 meter stub is about 16 feet away from the feed point. If you can get the stub horizontal then it would work well as an inverted “L”.
Is your shack window near the house edge? Attaching the box there and running as a sloper would work better. If you give me a number I can give you a call and make better suggestions. Email me direct at qrpm at aol.com.
73 for now,

I am in a similar situation than the original poster. I am thinking about an inverted L configuration with the vertical part being about 9 meters long and slightly sloped (somewhere around 30 degrees).
I am thinking about running the antenna just below the roof for the whole length of the house. Then it would pass around the corner of the house and go down along the wall, to the window of the room where I would keep my rig. Does this sound like a reasonable solution? Would it work? What would be the drawbacks of it?
How “far” need to be the stubs from the main wire? How many degrees minimum? If I find a way to keep them horizontal, would that work or is it going to be sub-optimal?
I also would like to know if it is possible to tune to non supported bands (for example 17 meters) with an autotuner.

I have a similar question. I live in a HOA restricted neighborhood. My house has a concrete tile roof and is 54′ gable to gable. I could either droop the final 10′ of wire down on the far end of the house. Or I could shorten the antenna to 54 feet and use an antenna tuner at the balun box. Has anyone tried anything similar?
