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 Zealand is a serious contender for this. You can even hire a 'motorized camper' and do your own thing in our clean green country. Summer comes in late January, ideal time to visit. Don't forget, we drive on the left side & there's no tipping.

>>>>>>>> WANT MORE Receive? HERE'S a couple of simple methods that give big results.

Method one:- Use 7/8 or thicker 'corrugated coax' from Shack to Antenna coax juction, here use  5/8 or 7/8 inch low loss flexable coax to your Antenna if it is a rotary array as Corrugated feeders cannt handle the turning movement. Back in the shack use the minimum number of inline accessories along with short lenghts 5/8 or 7/8 flexable coax with crimped high quality RF plugs that use gold or silver centre pins. This in effect now puts your Transceiver at the Antenna's feed terminals for a ultra low loss  low noise connection. To test... Disconnect coax at Antenna end so it now open circui and test directly Transceiver's coax plug end... You can 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.. the idea is to keep this reading very low... The start and finish readings now show you how many dB you have saved . Remember each 2dB lost in the feeder is the same as losing 1 element off your Beam antenna, so lets fix this issue for good with high quality plugs &feeders and good testing on your part....

Method two for more gain still:- Build a rig that can raise & lower your Array height. You probally already know your Optimin DX Path , so in this direction simply adjust your Array's height while looking for Positive signal variances over and above the start off reading. In doing so you may find several Peaks & Nulls. 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. Note the receive & transmitt variances should be the same. 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 on that distant SDR receiver and on your own receiver.

Computer simulation for best height offer 'indicative' height ranges, while my system allows exact factual gain extraction which is totally ''custom to your site'"  along with real time testing methods ....

Both aspects above if handled correctly can generate more then generious results...
