I have a simple dipole up about 25 ft. with about 75 feet per leg. I plan to use 300 ohm twinlead (hopefully not the Chinese stuff I saw in RS) and conn. a ferrite loopstick across the twinlead inside shop. I think a secondary (may have one already) of lower imped. would be ok to conn to radios on bench.
I would welcome any comments pro or con on this project.
I do plan to have a lightning arrestor of some type on lead in.

If this is for the AM band then don't even bother with the dipole. At 150 feet it's no where reasonant for the AM band. It will work but why go through al the trouble? If you are using it to test radios, any lenght of wire strung outdoors is fine.
The loopstick Q drops off dramatically above and below the band it is designed for. It will not reduce actual BCB noise but will reduce everything else. They are especially good in reducing fluorescent interference.
