Asking Price Shipping Amount Condition
$110.00 None Excellent

9:1 trifilar wound UN-UN on a large Micrometals core using high temp teflon wrapped wire with a temp rating of 350c

Picture was taken before unit was potted in marine fiberglass resin to waterproof it.

You get a complete antenna, transformer, wire and insulators for a random wire inverted L antenna.

Also makes a good limited space HF antenna (with proper grounding) T power up to 1kw SSB (conserative)

Bring in those stations you haven't been able to hear or make a HF antenna in a limited space. Or use it to feed a vertical antenna!
