Tuesday 19th March – Our next Presentation by Dave G3ZXX.

The Talk is entitled “The Dipole, why it’s not always the best”

It looks at ……
how many Amateurs install their MF/HF Dipole and how they think it will perform versus what is actually happening. The several variations on the dipole, for example the Doublet, Windom and the much used and miss-understood ‘G5RV’.
the types of ATU’s in use and the rights and wrongs of their use.
an interesting simple efficient variation which very few people know about ………………
There is no demonstration with this one, just the computer presentation.

Hopefully, that will fit the bill.

73, Dave G3ZXX

 

Due to a Parish Council Meeting at the hall, there will not be a Club meeting on Tuesday 13th February.

Following on from the really interesting Yagi/Beam presentation by Dave G3ZXX in January, Club Treasurer Dave G8TTI was inspired to finish his DK7ZB Based 144 Mhz Yagi on a 5m Boom.

Dave G8TTI said the following:
“It’s based on a DK7ZB design with a bent Driven Element. It offers 12.2dbd gain on a 5 metre boom. It’s optimised in Yagicad which is a program by VK3DIP. I switch polarity using a relay and so can easily alternate between horizontal and vertical. I built it in the hope of over coming polarization loss using EME. I’d rather like to have four of them stacked but that’s for another day”

Here are some photos of Dave G8TTI’s new homebrew Yagi

And up in the air and beaming Lunar!!

We wish Dave every success using his new antenna and thank Dave G3ZXX for the inspiration to get it done.
