[TowerTalk] 20m monoband Yagi height

[Robert Gerace]

Please forgive my inability to figure out how to search archives by subject as I have to imagine this is a common question. 

Understanding the best answer is “as high as possible” and the second best answer is at least one wavelength...

I wanted to ask about some real world experience between 50’ and 66-70’...

Specifically: given the same antenna, same QTH, same general point in the solar cycle...

Has anyone had a 20m monoband, trapless beam at ~50’, then raised it to ~70’ and seen enough consistent improvement to justify the effort?

Background:

Given my QTH I have about 55’ to tilt my (in process of permitting) tower. If I want to go higher I’m clear to 70 easy. However it will require telescoping (e.g. lower to 55, then tilt) to be able to service from the ground — a requirement for me.)

The cost difference is very substantial all the way around: purchase, shipping, footing, installation). 

So I’m wondering if it’s worth all the time and trouble to get an extra 15-20 feet?

Background: I’d like a big signal, would like to have at least a 50-75% chance to bust most pileups... even if it takes patience...but I’m a casual DXer who after 44 years is getting serious about 20m CW DXCC. 

I’m not trying to be the guy who is first through the pileup or even places in a DX contest... but I’m tired of being the guy who can only reach for low hanging fruit. I want to work some more dopamine inducing DX and maybe turn in something more than average on contests. 

I live in NE FL, a mile from the beach, on very sandy soils, and have oak trees at 45’. 

Any insight appreciated. 

Thanks es 73
