original plea!<br>
<br>
I go the thing (80m EFHW) up this weekend following the design on
the OCFMasters website. Well... partial success. Granted, I'm
still waiting for the cap that goes across the primary at the 39:1
matching xformer/balun and that it is still very low, only about
8ft above the ground at the lowest point.<br>
<br>
The SWR at a useful point in the band (measured at the choke) is
OK on 80, 40 and 10, but really quite bad everywhere else.<br>
<br>
The missing cap is due from Digikey today. Stay tuned... (pun
intended)<br>

<div dir="auto">The 'effective electrical length' of the wire is
influenced by several parameters. One of them is the physical
length. Others include the type of wire, the insulation and the
height above ground. Hard to know what that little loop from the
main wire to the balun will do. You don't actually know that
electrical length for sure until you measure it with a signal
applied from your antenna analyzer or transmitter.

is to add length of you cut it too short.<br>

<div> <font face="Verdana">OK, time for newbie question...<br>
<br>
When measuring the length of a wire antenna element, such
as an EFHW, do you include or ignore the bit from the end
insulator to the terminal of the balun?<br>
<br>
Yes, I know, it will only amount to 4-6 inches but I'd
rather get it right from the start than have to add/trim
later.<br>

Thanks!<br>
