Hi,

Jake,

Jake starts with an interesting assumption: HF6V or ANY vertical.
HF6V is not the same as any vertical, as the 1/4 wl on 20m 75 own coax which was delivered with the antenna acts as a matching stub on 20m.

I have the same question:
Is a choke needed, and where do I place it on a regular 1/4 vertical and where on a HF[6|9]V?

How do,



The thread on ferrites has been most interesting, but it leaves a question or 
two unanswered. Please be kind to an old timer.

The scenario: Butternut HF6V (or any hf vertical) ground mounted w/32 radials 
at 32 feet, buried just beneath the surface. The questions:

Is a choke needed on the feed line and if so, how many #31 snap on ferrites are 
needed for proper function.



AND are they placed at the feed point, or at the 32' point to match the radial 
length?



And please remember, be kind to an old timer who didn't do to well in algee.... um 
alger, um lets just make that math. <GRIN>



73 and Tnx
