i'm thinking about replacing my 102 ft G5RV with a ZS6BKW (optimizied) antenna.

it will be a a flat top configuration @ 40 feet and running directly east & west from SW Tn.

I am thinking I can get 5 HF bands without a tuner and the WARC bands too. I am not at all interested in working DX

anyone have any experiences with one of theses? Z<More audio>S6BKWZS6BKW

The antenna tuners built into modern HF rigs generally only work up to 3:1 SWR. So the G5RV type antennas are more difficult to tune then with an external tuner.

Check out the SWR graph at G5RV Antenna

Also in a many cases I think that long runs of coax have enough loss that it masks the problems. The SWR meter back at your radio may show a decent SWR but a lot of the watts you transmit aren't making it to the antenna.

By comparison the ZS6BKW well work well for 40, 20, 17, 12 & 10.

The consensus of articles I've see is that the 102' G5RV is at its best on 20 meters and a good tuner well match 80 and 12 meters but it is a terrible 10 meter antenna.

    My first thought was the i.r.s. may be interested in a long term money making scam without proper taxes being paid..probably more than electronics involved.

    My first thought was why hasn't someone paid him a visit. I mean, his address is posted above.

    Good news! I opened an appeal case after eBay sided with superhawkwss6. I also opened an IC3 case & sent that information to eBay. Within an hour they responded, reversed their decision and returned all of my money. Unfortunately, superhawkwss6 stole my CB radio and eBay will likely not suspend or close his account, but rather allow him to continue his criminal activity. I think I'll still file a report with our sheriff's dept (the sheriff is a friend of mine) though I know this type of crime isn't worth their time. This guy needs to be stopped and I'm certainly going to do my best to make that happen.
