Magnetic Loops are cool antennas, and if you want to get on the low bands in a small space with decent efficiency, they're one of your best options. If designed carefully, they're very efficient, but there are trade-offs. They're relatively narrow banded, so they require frequent retuning via a variable capacitor.A good quality balun (transmission line transformer - BALanced to UNbalanced) is required for the antenna to work properly and to match the impedance, which is higher than that of a resonant dipole. For lower antenna height, usually below 40', a 4:1 ratio is recommended; for higher antennas, a 6:1 ratio is recommended.21. Location. EDGERTON. Jul 27, 2021. #1.

Jun 24, 2020 · An Ameritron 5-port remote RF antenna switch I had on hand was put into service; it did need a separate small-gauge multi-wire control cable to be run to the attic. Although the switch isn’t rated for 70cm operation, the manual says it will work on that band with a bit of acceptable loss. W5GI Mystery Antenna is a multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. Very compact 2M/440 base antenna, easily hidden. Perfect for outdoors, attic or closet installations. Mount pipe acts as shroud to protect the antenna/coax conection from the elements. Unique “split-thread” lock bolt is supplied to attach the antenna to the mount pipe, the threads compress when installed to keep the bolt from backing out.
