What kind of of multi band antenna are you building ? Off Center Fed, G5RV, Long Wire …………? I believe the informal Tech Talk Zoom meetings are happening on Wednesdays, at 7:30pm until……, meeting ID # 549 621 524, password w4nc (small letters). There are antenna experts there.
An Off Center Fed dipole will give you 40m-10m with a 4:1 balun. Here are instructions . https://k8jhr.com/files/ocf_dipole_final_analysis_and_report_1_odt.pdf
Or, build a longer one for 80-10. Our club meets on the second Monday at the Red Cross Blood building on Coliseum Drive, and someone will be happy to help you. Sam, NI4TG
