I think he's addressed this subject. I like #14 or #12 insulated. Solid or stranded choice depends on your strength and flexibility requirements. Thicker wire gives a slightly better bandwidth at the cost of weight.

For high power, double-up on size 240 cores. Youtube "TRX Bench" channel has a great 4-part video series on building baluns. My experience tells me that if I want a long lasting, reliable balun (good quality components and workmanship that withstand the elements), it's more cost effective to buy off the shelf from Balun Designs or equivalent. (The amount I saved wasn't worth the trouble.) Of course, making my own is fun and educational; but I now buy my baluns from Bob.

I found a MFJ model - MFJ-1982HP is rated for 800pep https://mfjenterprises.com/products/mfj-1982hp This antenna is available in three power ratings: MFJ-1982LP – 30w MFJ-1982MP – 300w MFJ-1982HP – 800w Anyone have experience with this antenna? A couple of questions – 1. If you have experience with high power (>= 600w) transformers for EFHW antennas, what design did you use * Core type and number of cores * type 53 has a higher curie temp as opposed to type 43.... * Wire AWG? * I see a number of YouTube videos recommending 56:1 as 49:1 * Comments? 1. What is your recommended wire for the radiation element? * Material – i. Copper over steel? ii. Hard-drawn copper? iii. Other b.AWG? i. Number of Strands & strand count? c. Jacket material d. Other? Your guidance is appreciated! ’73, Mike KK5SC ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/bvarc@bvarc.org/ ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/bvarc@bvarc.org/ -- Rick Hiller e-mail: rickhille...@gmail.com<mailto:rickhille...@gmail.com> Cell: 832-474-3713 Physical: 9031 Troulon Drive Houston, TX 77036 ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/bvarc@bvarc.org/ ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/bvarc@bvarc.org/ ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/bvarc@bvarc.org/ ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org Publicly available archives are available here: https://www.mail-archive.com/bvarc@bvarc.org/
