I'm at work right now so offhand I'd guess they are 5/8" bolts as they are pretty stout. You could go over to the Tek2000 website and shoot him a email and he could probably tell you what size bolts they are. Since the dish is made in China it's a good chance they are metric bolts and not SAE. __________________ 10' Tek2000 mesh dish, 24" Venture actuator, ASC1 mover, Titanium LNB, Icecrypt CHD3750, Zgemma H7AC 4K, Octagon SF8008 4K, 1.2 meter motorized KU band dish.

I ordered me a new bolt kit and a ASC1 for my setup.. so hopefully I can get it figured out.

I took today off of work due to the severe weather. With a rare day off I want to try to tune this TP. I currently get zero on the signal meter for DW. I have not set up a dish from scratch before so this is a learning experience. The weather is not suitable for checking the f/d and centering of the feedhorn. What else could I try as far as tuning the dish at least to get a signal to register? Currently SES 3 ku is coming in fine on both polarities.

Puzzled... pull down or push up on your dish and monitor the signal to see if it increases at all. It might be a simple adjustment to fix your problem.

I pulled down on the dish while my son was watching the TV screen and the signal jumped from zero to 94 on the DW transponder. I was really happy about that! But once I let go the signal disappeared again. Any idea what adjustment needs to be made? __________________ Michigan state. 12' Paraclypse rescue & restoration.

Keep in mind that you'll need an antenna with < 2 deg Beamwidth. The sat next to 103w is rather strong and has some radio muxes within the same spectrum as the DW mux. 103w 4140 V 30000 with a bandwidth of 36 MHz So on 103 w 4122 thru 4158 MHz is occupied by the DW mux. Next door at 105 W on the same polarization you have: 4122 V 2400 BW of 3 MHz 4132 V 5000 BW of 6.75 MHz On smaller CBAND antennas with a BW > 2 degrees, these two signals will present themselves as interference to 4140 V 30000 on 103W. example, here on the PT 7.5 antenna 105w 4132 V 5000 12 dB BW 6.75 MHz 4122 V 2400 13 dB BW 3 MHz 103w 4140 V 30000 at FEC 5/6 is only 9 dB, which isn't good enough to lock. edit: I believe DW moved to 4140 V 30000 about 1 1/2 yrs ago, while the radio signals moved to 105w just a little over a year ago. __________________ Perfect 10 7.5' mesh Chapparal C/Ku Co-Rotor feed, Norsat 8115 CBAND, Norsat 4106A Ku Thomson Saginaw Actuator, Vbox positioner, Home Brew Polarotor683 Servo circuit.
