[TowerTalk] TowerTalk Digest, Vol 90, Issue 27 Re: Force12 C-19XR and Warc-7

[Mark Hooper]

Roger,  The Delta 130 is a coil loaded 30M element that is now being 
used instead of the old EF-130 linear loaded 30M element on the Warc-7.
It is easier to assemble and much easier to tune than the EF-130.
