I have a friend that has made his own 220 MHz version of the DB antenna, the worst problem he had was getting the harness to seal. I told him about Scotchkoat and he has not had a problem since. By the way, the Vapor Block coax does not do much for me. If the coax is sealed correctly you will never get water in it. All Vapor Block does is make it hard to work with, it still lets water migrate to the lowest point in the coax which is usually the Heliax connector.
The problem with my friend right now is he is 76 years old and his mind seems to be going away. He was supposed to build me an antenna but has forgotten about it. The two antennas (1 TX, 1 RX) on his 500 foot tower have been up for about ten years with no problem.

I know of no person who has "properly cloned" one of the famous DB-Products Vapour Block Cable Phasing harness assemblies for their multi dipole assemblies. Maybe someone on the group and I sure would like to hear (read actually) how their end product harness actually performed. I've got a few single high range 200 MHz DB Dipoles around... so the spacing and coax harness are the big beast. After spending so much time chasing the DB-224JJ information down I'd probably buy and use something else, which I have done. I'll keep the JJ Model in my mind as I pull down a few more of the Nationwide 220 ACSB Trunking Systems in the spring time. Since Hustler beefed up their 224 MHz G6/G7 Antenna I've had great results using them at repeater sites. No more birds peeling off the ground radials. cheers, skipp > "Tom Manning" <[EMAIL PROTECTED]> wrote: > Hello Skipp > As I have suggested before on this subject, it would seem to me that if someone would measure a DB224JJ very carefully and give us the dimensions of elements, spacing and harness most of us are capable of modifying a DB224 commercial model for 220Mhz. This would solve a problem. Thanks de Tom Manning, AF4UG Yahoo! Groups Links No virus found in this incoming message. Checked by AVG Free Edition.
