NEWS:  MODEL 807  AVAILABILITY

PLEASE ADDRESS ALL QUESTIONS ABOUT AVAILABILITY TO:

 

Email:  Info@Spiderbeam.com

Production of the  807-L & 807-HD is going on NOW.

 

 Spiderbeam has informed us of the following:

  • There are some component availability problems.
  • 25+ baluns have been built, but are not yet in an enclosure.
    • These can be used in both the -L or the -HD versions.
  • Waiting on pre-drilled enclosures to arrive.
  • 25+ sets of wires for the "-L" are pre-cut and ready to attach, once the baluns are mounted into their enclosures.
  • Wire for building the "-HD" is in stock and can be cut and ready within a couple of days.  This won't be done until the missing components are in stock.
  • Several hundred RMU printed circuit boards, fully populated with resistors and capacitors, are now in stock and waiting to have leads soldered onto them.
    • These can be used in both the -L & -HD versions.
    • Due to component availibility problems (SMD Caps), the 75m version of these antennas will initially have a power rating of just 300w SSB/CW (this version only).  Sorry but the caps we planned to use in this version are simply not currently available.

 

 

 

Aerial-51's design and construction of the first  "807-HD"  prototype is completed.

  • Same balun and RMU as the 807-L, 
  • but using much heavier-duty (and heavier) wire - CQ-532.
  • Next step: Adjustment of the length of the wire legs.  
  • Then: hang on a pole in the field and run first set of measurements to determine final wire lengths, which will be slightly different from the -L due to different velocity factors of the two wire types.

Spiderbeam will begin production of the "HD" immediately following completion of the current run of 807-L antennas.

 

BOTH VERSIONS OF THE 807 WILL BE AVAILABLE SOON.

 

NOTE:  The only technical difference between the 807-L and 807-HD is the size (and weight) of the wire used in the wire legs.  All else is exactly the same -except the price.

 

Which one is for YOU?

  • The 807-L with its thinner wire weighs less and is better suited for short-term portable use.
  • The 807-L's thinner wire is nearly impossible to see when mounted 10 meters (33 ft.) in the air.  Great for stealth installations.
  • The 807-HD's thicker wire makes it much more suitable for permanent installations where the WX has lots of snow and/or ice, and wind.
  • The 807-HD's price has not yet been set . . . because Aerial-51 does not sell anything.  We only develop products.  Spiderbeam will set the price.

 

For our North American Users:

 

Special capacitors are currently on order which will enable us to build RMUs capable of setting the 80m resonance at about 3.900 MHz.

 

This was not possible when using the capacitors which we use in European versions and US versions with resonance at 3.800 MHz.
