I have built both this antenna and KV5R's original design. They both work perfectly. I use the tape on PVC version (KV5R's
original design) as a field expedient antenna for events or emergency deployments. My version is installed on my home at about
15 feet above ground as my primary VHF/UHF antenna for my Icom IC-706MkIIG. They both perform very well all across both bands.
Note the 4-5 turn common mode choke at the base of the antenna. Good practice even if not seriously necessary
