Re: New Antenna for the FT-817 and other QRP portables...
Am I missing something here? Isn't the *point* of the whole elaborate joke obviously to lampoon claims for small antennas on the FT-817? Frank AB2KT

Re: Slinky Spring Dipole.
Slinky... In an older ARRL Handbook (1979?) I recall a discussion of helical HF antennas. The strong suggestion is to use capacitance hats to, among other things, broaden the "sweet spot" -- for

Re: Slinky Spring Dipole.
Ray: I used a "Slinky" antenna running QRP CW from an appartment a while ago. The one think that's obvious when you start to play with it is that the tuning changes drastically with even small

Re: Slinky Spring Dipole.
I could never get slinky antennas to do that well in field operation using QRP. Also, they droop. To cure that in the dipole configuration, you need a slinky bra. -- Bil KD6JUI
