Regarding recent conversations on 5/8 wave vertical antennas:
https://vk2zoi.com/flower-pots/ Open this website with a browser and open one of the articles on "Double 5/8 Flower Pot" verticals. This 5/8 wave vertical dipole may be constructed using some RG-59 coax and a bit of soldering. The antenna uses the coax itself to form 1/4 wave sleeve transformers to convert the dipole's 100 ohm feed point to 50 ohms. The coil of RG-59 is used to choke off the sneak RF path on the outer portion of the coax. It takes a bit of thought to understand this system but it actually works well. The entire antenna should be covered using a 1" section of PVC as shown else the SWR will rise when it gets wet. I have implemented the simpler 1/2 wave "Flower Pot" vertical using RG-8X coax for my 2 mtr. base station antenna. I currently use a QRO 1/2 wave vertical dipole on 20 mtrs. using the same principle. 73, Gary Sitton, K5AMH gasit...@comcast.net
