The rear element is λ/2 from the rear plate, so any reflected waves from the rear plate are in phase (effectively increasing the signal), the front element is λ/2 from the rear element so you have maximum deflection between the two elements (hence the diff amp). The 'beauty' of this is it is...

If you feel comfortable with it then some fuse wire in series with a 10 ohm resistor might do the job. Just make sure the power rating on the resistor is sufficient. More impotantly though, perhaps it would be prudent to find out what caused it to blow first!

It reminds me of an idea I had for an LNB many moons ago. Chances are I'll never get around to build it, so perhaps it might interest someone.

Can you set the modulation to 8apsk?

It looks as though one octant has more modultion than the others, this is probably because more information is being transmitted in that octant.

From a user's point of view how does it compare to the (much cheaper) TBS 8921?

dvbsupport (.net) has HD (codec) packs - that I think are free & may be worth checking out.

Nero codecs will decode 4:2:2 in SD - not sure about HD, plus a whole lot more. Traditionally I have found Cyberlink codecs to be the best quality, low resourse codecs to use (in SD).

The idea is to keep the cable cool, if a cable is left in the sun it will get warm and noise will increase.

It's not something I do myself and would be a little reserved about thermal shock, that said, I appreciate the benefits for fringe areas where signal to noise is critical. One other thing you might want to consider is your coax run. If you bury your coax you will see noise reduce - particularly...

Without looking it up, I seem to remember from college days that noise is proportional to the square root of temperature (measured in Kelvin). (In a receiver noise is proportional to √4KBTR)

It's more than likely the transmit system has an automatic level control, so if solar noise is high (during the day) or if there is rain fade - the transmit signal will increase. At night the transmit signal will decrease (in order to maintain the same signal to noise in the designated catchment...

And the 6984 doesn't support blindscan. Ah well, it was a nice idea while it lasted.

It would be interesting to know if Crazyscan could use both ports of the 6925 (with a dual LNB) or all 4 ports of the 6984 :eek: to cut down scan time. If not, it would be a very interesting upgrade / development for the future.
