Roland contacted me today with photos of his homebrew 6el 50MHz LFA the build sizes of which can be found on this site. The 6el is a verypopular size is it is not too big and heavy yet gives stunning performance.
The very latest version of this antenna is available through my company InnovAntennas http://www.innovantennas.com/antennas-a-accesories/on-line-shop/view/productdetails/virtuemart_product_id/196/virtuemart_category_id/3.html
Or just build one yourself. Enjoy!
