[VHFcontesting] Looking for a 1.2 GHz antenna.

Have used the Directive Systems Loopers here in Florida's weather 
with no problems.  The 47EL 902, 55EL 1296 and 76 el 2304 went 
through 3 Hurricanes here in Orlando with no problems.  The 112 EL 
one for 3456 has only been up for little over 1 year but performs 
well with no problems.

As to M2, Their antennas also hold up well, I have their antennas up 
for HF (KT34M2) and VHF - 6M7JHV, a pair of 2m-5WLs, 222-7WL and a 
pair of 432-13WLs.  The only problems I have had was one broken 
insulator (and a few cracked ones on the KT34A before I did the M2 
Mods on it.  The rest weathered the storms well.

One Caveat, Make sure the connectors are sealed with RTV or Coax 
Seal.  Here in Florida's wild swings of summer temperatures,  I have 
seen the Cavity in the "N" connector fill up with water from sucking 
in moist air when the connector cools down in a summer 
Thunderstorm.  I have good luck with Andrews D Connector 
Weatherproofing Kits Andrews Part Number 221213(it helps to have 
friends in the Cel Tower business).  The kits contain Butyl rubber 
tape (commercial grade Coax Seal) and Scotch brand Plastic tape.

One layer of the Butyl Rubber Tape to seal the connector and the 
plastic (3 layers to complete the job.  Andrews also makes a "Cold 
Shrink" product  for sealing splices that I can't vouch for.    I 
have never had water intrusion on any cable here in Central Florida's 
Greenhouse weather using this method.
