Hi Bill,

for a homemade "Elk" style log-perodic antenna covering both the 2m and 70cm bands see this homemade antenna (with bilingual instructions in German and English) link:

The text above is mostly self explaining and very simple and cheap to construct with some basic tools on hand.

This antenna is slightly larger than the Elk (15 inch longer boom length) which results even in a higher gain then the original Elk design. Maybe this gives some desired extra punch for eventual indoor operation.

Good luck,
