9-band vertical covers 80/40/30/20/17/15/12/10/6 Meters
No radials - No traps - No ground - No tuning
Instead of typical traps, Hy-Gain’s resonators are placed in parallel not in series. End loading of the lower HF bands allows efficient operation with a manageable antenna height.
With the AV-680, you get the same great traditional performance of the AV-640 on 6 through 40 Meters plus top-to-bottom capability on 80 and 75 Meters.
It's a great way to join new local nets and roundtables, explore the 75-Meter DX window, or add exciting digital frequencies to your operating repertoire. Simply pick the band segment you wish to use, set the 80/75 Meter resonator, and you're in business. No ground or radials needed -- Effective counterpoise replaces radials, end fed with broadband matching unit.
Automatic bandswitching -- Single coax cable feed, each band is individually tunable, wide VSWR bandwidth.
Sleek and low-profile -- Low wind surface area, small area required for mounting, mounts easily on decks, roofs and patios. Built-to-last -- Hy-gain’sPatriot series antennas boast ahigh wind survival due to its sleek, but sturdy frame. The matching unit is made from all Teflon insulated wire.
Top Loading: Parallel resonators -- best vertical-element efficiency.
Full ground independence: No unsightly wire add-on radials.
Top-to-bottom 3.5 to 4.0 MHz coverage:
Pin-point fine-tuning accuracy for rock-bottom SWR on any frequency you choose.
Single coax feed . . . and with 100% automatic band selection!
Adding 75/80 Meter coverage without compromising the Patriot's classic performance, ground independence, and tiny footprint was no small task. Yet, the AV-680 size, weight, and wind loading are nearly identical to the AV-640 with no unsightly radial extensions, traps, or top heavy vertical structures to render it less attractive or unsafe.
Band selection remains fully automatic, all components handle maximum legal power, and you won't need a tuner with your solid-state rig.
The AV-680's Expanded-Frequency MatchboxTM circuit ensures low SWR readings on every band, along with an upgraded balun design that concentrates all of your power in the antenna where it belongs!
