Hi Pat,

The only LPA for amateurs that comes close to covering what you're looking
for is the 7-10-30LP8 'SKIP LOG' LPA by M2.  Here are it's specs:

Model  	7-10-30LP8 'SKIP LOG'
Frequency range 	10 to 30 MHz continuous and a separate
frequency tunable from 6.6 to 8.6 MHz
Typical gain 	6 dBd 10-30 MHz and 3 dBd @ 7 MHz
Front to back, Typical 	15 dB 10-30 MHz and 6 dB @ 7 MHz
Beamwidth 	65° E and 75° in H plane
Feed impedance 	50 Ohms unbalanced into 4:1 Balun
VSWR 	1.8:1
Input Connector 	SO-239 standard. N type available
Power Handling 	3 kW standard, Higher available
Boom length and diameter 	29.5 Ft X 3" X .125 wall
Maximum element length 	46 Ft.
Turning radius 	28 Ft.
Wind Area / Survival 	13 Sq. Ft. / 100 MPH (125 MPH avail.)
Weight / ShipWt. 	86 lbs / 100 lbs TRUCK ONLY

The M2 webpage is at:  http://www.m2inc.com/

Or, you could go with a large, expensive, custom built LPA that covers
something like 5 to 30 MHz that's available from certain contractors, such
as Array Solutions.  See webpage:

But, I doubt that you'll want to spend the  money to put up such a LARGE
array - like Ft. Bragg did.  Personally, I like the M2 skip log.  I'm even
considering it.

73 and good hunting.
