The discone antenna is well known through out the world for giving excellent performance. Your scanner is only as good as your antenna. This antenna will increase the range by upto 70%. 4 antennas are included on the top of this antenna. Each one is cut to a different frequency so that you get the best performance that is possable. Normal discone antennas have parts of there range where they are not working correctly, this design gives optimal frequency range with no disadvantages! * Well made with the finest materials * Comes with a short mounting pole and bracket * Top performance with 4 different antennas for the best reception across the widest range There is a full no quibble 12 months warranty if there are any problems we will replace the unit for you! Get the best performance without drawing attention to yourself with an outdoor antenna! No cable is supplied with this antenna. If you would like cable at an extra please specify the amount of cable you need at 0.75p per meter. Wach plug is 0.80p and we fit them free of charge. This is a review of the antenna The V1300 is unlike any other disconne i have seen. Above the cone are four vertical whips, giving the V1300 both vertical and horizontal active elements, pre-cut to set frequency bands. The V1330 is made of good quality, stainless steel and aluminium and on unpacking the parts i was very pleased with the overall standard of engineering. The only change i would suggest to the design of the cone. I would like to the base of the cone threaded to take the top of a screwed support tube and make an already good bit of engineering outstanding. Although it would probably raise the overall cost a little, it would be worth it for the overall improvement to the waterproofing of the coaxial mount point. The coaxial cable and PL-259 are fitted inside the cone after passing through the support tub, giving good waterproofing. This needs to be done before any of the radials and active elements of are screwed into place. Once this is done the disconne is ready to mount out in the open, as high as possible and away from all power lines. One golden rule when putting up any disconne is use UR67 or similar coaxial cable to cut down on feeder losses at higher frequencies. Test results taken against two other disconne antennas, one without a vertically polarised section and one with such an element, showed that from 50 to 107 MHz there was no difference between the three antenna. On the 108 to 136 MHz a gain of 4dB over the two reference disconnes was measured. Between 137 and 175 MHz this rose to 7dB falling to 2dB between 176 and 525 MHz and steadying at 4dB between 526 and 1300 MHz. Using the Sky Scan V1300, I carried out listening tests at my QTH in Bristol. On both the v.h.f. and u.h.f. airbands i was able to monitor air to ground an air to air both ways, at a distance of over 300 miles under far from ideal conditions during the first half of October 1990. During the tests it was pleasing to record after darkness on several days, a number of military in-flight transmissions on frequencies never before monitored by myself between 176 and 525 MHz. The receivers i used to carry out the tests were a Kenwood R5000VHF, Signal R535 airband receive, Kenwood RZ-1 , Icom IC-R100 and a Realistic Pro 2022 scanner. Not much difference between the receivers was noted during the tests. It all adds up to the fact that your receiving station is only as good as your antenna makes it. From my tests, I think that you should get good results with the V1300 and any good scanner an the market today. The V1300 can be used for transmitting on the 144, 430 & 1296 MHz amateur bands, unlike many other wide band disconnes, if one of the long elements is replaced by an element 280mm long. This length would depend on the locality of the QTH and should only be done by a person with some knowledge of working antennas.
