options for 10m? Tarheel 200a, cap hat, 1ft mast, 70" whip

[mr_fx]

lets add it up


top whip >>> 70"

cap hat >>> claims it added about 40" effective length

cap hat extension >>> 12"

main mast >>> 48"

That makes it around 170" effective length while fully collapsed plus another 6" or so in connectors... that being said it's not quite right, it seems to run around 15m while fully collapsed

Remove the cap-hat and extension and see where it ends up resonant.

26mhz or so

If that's with the thing all the way collapsed, then I'd guess you'd need to shorten the whip just a 'touch'. No idea how much, but it won't be very much.

According to the mfg's site the antenna is usable for 3.5 to 26 mhz so shorting the whip should make it tunable to 28.

with a hit to lower band performance... not worth it... I can alway put up more antennas

That's up to you of course. The question is, how big'a 'hit' would 80 meters really take? Do you really use the bottom end all that much?

Yep yes you can.

Yep yes you can.
