I am shocked at how well the short 500 and 580 foot Beverage work. ... But after 3 seasons on top band I am convinced my station is NOT balanced. I must get a Amp !
That's because switching to your Beverage is like the other station (that you're trying to copy) after he's just switched on a big linear amplifier. It often gives that much of an improvement. Listening on the Beverages often requires that I run my amplifier to make stations hear me that can only be copied on the Beverage antennas.
If you think they work good on 160, you should try them on 80 and 40!
And that's also my situation (unbalanced) on 160 (I only have 100 watts on 160m). I can hear a lot more weak DX than I can work there. But we're working on it.
