You wanna be careful believing the advertisements of any antenna manufacturer, they aren't always the -complete- truth, sort of.
The purpose of the driven element is to supply and radiate an RF signal. That signal is then 'manipulated' by the other elements of the antenna. Each 'element' has characteristics that make it more convenient for use in particular circumstances. Those characteristics are both mechanical and electrical in nature. A particular element may do things electrically that make it very desirable but be so mechanically difficult to use that it isn't worth the time and trouble to use it. (That's particularly applicable for quads and everything associated with them, they are just 'bigger' antennas, a mechanical thing.)
All the elements of a directional antenna do not -have to be- insulated from the boom. (That includes the driven element, just depends on how it's fed.) The electrical differences between insulated from the boom elements and those that are not are not very 'huge' and can be compensated for. Which would be more convenient for you to use? Beats me, you decide. Which of those two types of antennas would be 'better' for your use? Beats me! You have to decide that one.
Have fun.

[QUOTE="W5LZ, post: 370671, member: 129"] You wanna be careful believing the advertisements of any antenna manufacturer, they aren't always the -complete- truth, sort of. The purpose of the driven element is to supply and radiate an RF signal. That signal is then 'manipulated' by the other elements of the antenna. Each 'element' has characteristics that make it more convenient for use in particular circumstances. Those characteristics are both mechanical and electrical in nature. A particular element may do things electrically that make it very desirable but be so mechanically difficult to use that it isn't worth the time and trouble to use it. (That's particularly applicable for quads and everything associated with them, they are just 'bigger' antennas, a mechanical thing.) All the elements of a directional antenna do not -have to be- insulated from the boom. (That includes the driven element, just depends on how it's fed.) The electrical differences between insulated from the boom elements and those that are not are not very 'huge' and can be compensated for. Which would be more convenient for you to use? Beats me, you decide. Which of those two types of antennas would be 'better' for your use? Beats me! You have to decide that one. Have fun. - 'Doc [/QUOTE]
