My Antenna's both M2

2M9SSB & 6M7 Models...

Note: Today System is 2M9SSB Stacked and 6M5X for 50MHz

The M2 2M9 is a nine element, computer optimized 2m beam antenna designed for either FM or SSB operation. The antenna features machined aluminum driven element shorting bars, CNC-machined T-match block which is sealed with a silicone-gel, sealed balun connectors, and stainless steel hardware.

The thrust bearing is seen on the top shelf in the picture to the left. The rotator is not mounted yet on the bottom rotor shelf. The safety latch is below the rotator shelf however the sping has not been installed at this time. It is in the latched position secured / resting on the rung below the rotor shelf.

Tower top section with GA25GD Assembly The tower is a 12" face triangular design using 1-1/4" steel legs and continuous 5/16" steel rod bracing. Middle sections measure 10 feet long, top sections are approximately nine. Sections fit together with a double-bolted joint. The tower is a guyed design; three anchors spaced radially 120° apart, are set out from the base 80% of the tower height.

Model A-1015-G 150 Watts Output SIX Meter Solid State Amp by Mirage;GaAsFET receive preamps gives you 20 dB gain; 150 Watts Output with 10 Watts Drive; 18 - 22 Amps at 13.8 Volts DC. Weight 5 lbs measures 12'X3"X5.5".
Model B1016G Two Meter 150 Watt Solid State Amp by Mirage; Pre Amp Gain 20dB; Drive .25 - 15 watts; Amps Max 25 at 13.8VDC; Size 12X3X5.5 inches

My Experience with Mirage, both units above... the preamp has a terrible NF and less gain than advertised! I always leave them turned off!

(I don't know of a radio manufactured that doesn't beneffit from a good outboard preamp)

The IC 746 HF / 50 & 144MHz ...

I highly recommend ordering the HSCU Option if you plan to operate 2 Meter WSJT Modes. It is soldered in and requires some skills.... get it done when you order!

This radio is a "low -end" unit in cost but a "Best In Class" Rig !
Note: Today a TS-2000 is being used for 2 & 6 Meters. The IC746 is now a
back-up radio and used on HF.

Adding it all up:

_129.00 Two meter 2M9SSB antenna
_309.00 Six meter 6M7 antenna
_290.00 Heliax Cable 120 Ft.
_339.00 Hazer Tram System
__69.00 Thrust Bearing
_612.00 50 Ft Rohn Tower
_560.00 Ham IV Rotator & Control Box
_349.00 6M Mirage Solid State Amp
_369.00 2M Mirage Solid State Amp
_240.00 ARR 2 & 6 Meter Rx Preamplifiers
1369.00 IC746 Radio HF & 6 + 2 Meters
__69.00 IC746 HSCU

Total is $4704.00 Less Power supply, connectors, jumper coax's, rotator cable,
RF Watt Meters, tape, cable ties, Soundboard Inteface, mask, guy wire ; so you go figure... add maybe another 1000 and what about the computer!

Hey it's still cheaper than a Bass Boat or RV !

The cost of assemblying a station is expensive. This is not a HP Station! I feel like my station is very modest but works well. I am able to work the World and a lots of MS! Cutting expenses should always be considered but study closely your needs vs. good operating practices and expectations!

I could have installed cheaper feedline for six meters... I could have eliminated 10 or 20 feet of tower height with some compromise in results... The Hazer system is expense but this is for those who don't feel safe hanging off the side of the tower...

This whole exercise was just for <Grins>.... & Note I upgraded to a Kenwood TS2000 after this was prepared.
