Re: Topband: yes virginia there is an antenna that works from 160 to 10
Wow! I want to stack two, and with a polarity rotator and adjustable spacing! You suppose there's a quantity discount? ;-) 73, Mike www.w0btu.com On Thu, Oct 4, 2018, 3:47 PM Sean Waite wrote: > What do you think, can we stack them for more gain? > > On Thu, Oct 4, 2018 at 4:22 PM N7DF via Topband > wrote: > > > > > 637P-1/1A Transportable (fixed direction) Log Periodic Antenna > > The 637P-1A is a directional HF Antenna for tactical or fixed station > > use. > > It can be operated from 1.5-30 MHZ with a gain of 7.5 to 12 DB between > > 4-30 MHz > > and below 4 MHz, it has an unidirectional pattern. > > The antenna is rated to accept power levels of 10 KW PEP or average. > > Model OE-85 is rated for 3 KW and OE-86 is rated for 10 KW. > > The only difference between the two models is the RF Connector on the > > balun. > > > > The average VSWR is 2:1 and the Front to Back ratio is 7.5 db to 12 db > > depending on several factors. > > > > It is 75' High (on a 80 foot mast) and requires a plot of land that is > 310 > > feet by 200 Feet > > It is designed to be stowed in a frame 57" x 35.5 " x 92" and can > > transported by truck or air. > > It weighs 1270 lbs. > > I tonly costs $55,000 > > _ > > Topband Reflector Archives - http://www.contesting.com/_topband > > > -- > > Sent from my Motorola DynaTAC 8000X > _ > Topband Reflector Archives - http://www.contesting.com/_topband > _ Topband Reflector Archives - http://www.contesting.com/_topband

What do you think, can we stack them for more gain?

Topband: yes virginia there is an antenna that works from 160 to 10
637P-1/1A Transportable (fixed direction) Log Periodic Antenna The 637P-1A is a directional HF Antenna for tactical or fixed station use. It can be operated from 1.5-30 MHZ with a gain of 7.5 to 12 DB between 4-30 MHz and below 4 MHz, it has an unidirectional pattern. The antenna is rated to accept power levels of 10 KW PEP or average. Model OE-85 is rated for 3 KW and OE-86 is rated for 10 KW. The only difference between the two models is the RF Connector on the balun. The average VSWR is 2:1 and the Front to Back ratio is 7.5 db to 12 db depending on several factors. It is 75' High (on a 80 foot mast) and requires a plot of land that is 310 feet by 200 Feet It is designed to be stowed in a frame 57" x 35.5 " x 92" and can transported by truck or air. It weighs 1270 lbs. I tonly costs $55,000 _ Topband Reflector Archives - http://www.contesting.com/_topband
