Review: Check rod straightness - Pretty good quality but the straightness could have been better.If you need to slide the coil that you wind onto the rod make sure to allow a little extra room between the coil form and the rod so you can slide the coil from one end to the other.If you make it too tight and the rod is not straight you may have trouble sliding it all the way. Ask me how I know!!!.
Review: Arrived whole, none broken. - All 5 arrived safe and sound! It took 2 weeks or more. I had to re-confirm my order. Not sure why. About 57 turns of # 32 gauge wire in the middle of one of these and a variable cap in parallel, 10-360pf at mid adjustment got 770 kHz AM station here in Albuquerque.
