Hi Terry
Can thoroughly recommend Justins designs
https://www.g0ksc.co.uk/2013-yagis/1...a/5el-lfa.html
All the AL can be obtained from Bunnings and the stauff clamps from hydraulic/mining suppliers in most state capitals.
I'm using his designs for 6m and 2m.
I have a 7 el LFA for 2m and have worked into Melbourne on digital modes and SSB to Hamilton in VK3 (all > 2,700km). From a backyard of an inner suburban Perth QTH.
Matching is almost perfect and its easy to build the ferrite choke "balun".
