261. Re: [TowerTalk] Using old concrete in new pour (score: 1)

I have poured concrete bases (4 x 4 x 4 ft) adding many clean hard rocks (fist size and larger) to the mix. I would not use old concrete or make it soupy. Doug I wasn't born in Saskatchewan, but I go

Now that's a clever idea. Make two adapters for each end of the feed coax and run AC up to the top temporarily on the coax. Pulling up an AC cord is much better than hauling a generator to the top. I

Well put Dave. I would put the CC A3 in a similar category with the TA33. Short boom on 20m and a relatively poor performer on that band but a pretty good performer on 10 & 15m. Ask me how I know. I
