80>10 EFHW Transformer 49:1
- I already had 2x FT240-43's (Fairrite) I bought from Enigma shop about 10yrs ago.
250g X 1.8mm Brocott coated wire (that's plenty)
2 X IP56 rated enclosure 100x100x50 from Screwfix. (second enclosure for other project)
1 X 100pF 6kv capacitor (blue) from Tekkikid on eBay.
50m X of poly coated flex weave, should not need more than 44m or slightly less.
2 X SO239 UHF Female Chassis Socket Square Flange Panel Mount.
10 X 2mm Duplex Wire clamps
4 X M6x12mm Eyebolt Stainless steel, used 1.
Having read a fair bit about Multiband EFHW's since our Buick reminded me they are a thing on both his threads,
£12 Homebrew EFHW
EFHW Tuner / LED SWR Bridge
I resurrected a project I meant to start almost a decade ago.
I'd intended to make a common mode choke years ago, bought all the bits and then lost interest in radio. I chose to make one based on reading G3TXQ (silent key now) site back then but read more this time round and tweaked a little.
Common Mode Choke
My reading lead me to a 9 turns of RG142 over 2 X FT240-31.
- I already had 3 X FT240-31 again from Enigma shop, I only used 2 though.
4m X RG142 from Engima shop 10 yrs ago (doubled in price now)
1 X IP56 Enclosure.
2 X SO239's
1 X M6x12mm Eyebolt Stainless steel.
Also worth having some cable tie anchors and good grippy cable ties.
BTW pulling RG142 tight is a complete bugger.
So pics attached for perusal.
And no I haven't deployed it yet as I need help sticking up the 44m or so antenna but when I do I'll let you know.
Thanks for the inspiration Buick.
