Ive read about the 64:1 being used on end fed half waves. I personally use a
49:1. I think its really going to depend on the impedance. If 3200 ohm, use
64:1. If its 2450 ohm go with the 49:1.

I agree on a 49:! Unun for HWEF use. For 1.8 mhz special care should be

If I remember correctly, my NF half wave for 180 was 262 with a 49 one ballon about 20 foot to 37 foot up in the air worked well with that much wire in the air. You’d be surprised what you can hear.Sent from my iPhoneOn May 6, 2024, at 7:08 PM, Gary Sitton via BVARC wrote:

Also, if the main portion isn't well above ground, you'll need to make the
length greater to account for the capacitive effect of the ground itself. L
configurations are very effective but avoid the inverted V scheme.

Hey John.
160M band would be about 259 ft long and because this band has such a low take
off angle, youd have to get this up pretty high.

Clue: HWEF (half wave end fed) so half of160 meters is 80 meters or about
250 feet!

So Rick, how long should I make these antennas and how long would it be to do
160?

Yes but a 40 mx half wave wire loads on 40, 20, 15 and 10. An 80 mx half wave loads 80 thru 10 including WARC.’s. Final matching uses the rigs internal tuner to bring things down further to an operable SWR.GL. W5RHSent from my i-ThingamajigOn Apr 13, 2024, at 1:48 AM, Suggs, Marvin (KTRK-TV)

Ok you hang the balun on the mast and string the wire to a tree? To work 20
meters, you’d have a 20 meter wire? Does that sound plausible?
Thanks
