Back in the mid 1970's, a high school buddy of mine had a Radio Shack VHF-hi band base station antenna. It used the same loading coil and whip as the mobile antenna they also sold at the time.
The radials were roughly 2.5 - 3 feet long each, but obviously shorter than the loading coil and whip.
Performance was very good, considering the poor sensitivity of RS's scanners back then.
I'd like to build something similar to this with an ASP-268 antenna.........specifically for 42-43 Mhz
reception.
Would anyone have any idea how long the radials need to be ?
66" inches is quarter wave, but I 'think' this is technically a 5/8 wave base loaded antenna.
They look identical to the gray-coiled CB antennas that were popular during the CB radio hey-day.
Antenna Specialists made a ton of them.
