Welcome to NEW ZEALAND. Population 4,500000

Located in the Southern Pacific Ocean. Six pocket sized cities house 90 percent of the population over two large islands. If you're looking for a recreational break then New Zealand is a serious contender for you. You can even hire a 'motorized camper' and do your own thing in our safe clean green country. Summer comes in late January, ideal time to visit. Don't forget, we drive on the left side of the road, no tipping and yes, your Visa card works well here.....

>>>>>>>> WANT MORE Receive?????? HERE'S a couple of simple ways that work very well.....

Method One:- Use 7/8 or thicker 'corrugated coax' from Shack to Antenna main coax juction, here use  5/8 or 7/8 inch low loss flexable coax to your Antenna if its a rotary array. Corrugated feeders cannt handle  turning motions. In the Shack use the minimum number of inline accessories along with short lenghts of 5/8 or 7/8 flexable coax with crimped high quality RF plugs. This in effect now puts your Transceiver at the Antenna's feed terminals for a ultra low loss, low noise connection. Test loss the start and finish loss results as follows:-  Disconnect coax at Antenna end.... it now open circuit etc and carry out this test from the Transceiver's coax plug end... use a digital Vector meter or a simple MFJ-259 analyzer. Select coax loss mode and sweep the frequency of operation while reading the feeder loss in dB, while the far end is open circuit.. The idea is to lower this reading from start to finish... The last reading should show you how many dB you have saved, every 2dB saved or gained equates to the gain of one element on your  Beam Antenna or more !!!!!!!

Method Two:-  For more gain still:- Build a rig that can raise & lower your Array's height. You probally already know your Optimin DX Path direction.... so in this direction simply adjust your Array's height while looking for Positive signal variances over and above the start off height reading on a distant receive signal you have tuned. In doing so you may find several Peaks & Nulls on this signal while height adjusting. Once a peak is found, simply cross reference this peak with your TX signal via 'w.w.w.remote SDR dot org'. Find a suitable remote SDR receiver thats able to hear your signal, tune it to your transmitters frequency & note all the positive variance as you raise and lower your Antenna while transmitting. The receive & transmitt variances should be equal. This suggested method is a basic cross reference test for both RC & TX and confirms the new vertically height tuned position as the most effective.  The results gained here can be simply dramatic to say the least, especially if you have forward slope paths in direction testing. Computer simulation for best height offers 'indicative height ranges' which is a positive height indication for you, while my system allows factual gain extraction for your site with self testing methods to prove the point from start to finish ....
