40M Antenna Comparison (yes, again)

I have been wondering why my silly Inverted Vee has been beating my UrbanBeam up 46 feet on 40M this summer. Noise is one issue – the horizontal antenna has been very noisy. The Inverted Vee has a higher take off angle – as does the UrbanBeam on 40M when it is “only” up 46 feet. I can see that low angle arriving signals…

The 40M “Shorty 40” Will Have to Wait

I’ve decided the best antenna for me is the one I have – The UrbanBeam After running a bunch of EZNec plots – on 40M – and then on several bands above – I realize that the best antenna for me is the one I have. Getting it up to 65′ will be plenty good enough for my needs. As much as I would…

More 40M Antenna Comparisons

The 2 element yagi up 65′ would be a great antenna – out performing a dipole by about 4dB The plots do mirror what I have tested on air – the DV-40-P phased verticals were better than the UrbanBeam up only 35′ feet on the ALM-31. The UrbanBeam starts to look better than the DV-40-P at about 45′ up – which is where I…

40M Antenna A-B Testing

The DX Engineering DV-40P phased vertical array Before I take down this vertical array, I will take some A – B measurements. I will establish a baseline between the UrbanBeam at 34-ish feet and the phased vertical array. Once the AB-577 gets the UrbanBeam up 5-55′, I will take new measurements – between the phased vertical array and with the antenna higher. The areas…
