20 feet of lightweight RG-174 coax. Wellbrook DC interface module for the ALA1530. 3.0 Ah LiFePO4 rechargeable battery for the Wellbrook antenna. 15 foot long section of high grade "Times Mfg." LMR-600 coax cable with PL259 connectors (bought from Ebay already assembled/soldered) Fold-up beach mat. Having had a WellBrook Loop ALA1530 for some time, I accidentally transmitted into it during a moment of madness where I wasn't using the RX antenna connector. I had been very impressed with the performance of the loop on LF frequencies, such as on 472 kHz and 1.8 MHz, and given the cost of a replacement, I decided to attempt a repair! 手動制御系における操作者の開ループ整形特性の 解析と ツール伝達関数の安定性に基づく人間一機械協調作業系の制御系に関する一考察 稲葉 毅 , 松尾 芳樹 計測自動制御学会論文集 39(10), 961-969, 2003-10-31 I've been using the ALA1530S+ for 3 days now and in a word "OUTSTANDING". It is mounted on a 6' tower with a rotor. Overall height is 15'. I have a Flex 5000 SDR which has 2 receivers, both of the same quality. Dual pan adapters allow me to also see the signals for a visual comparison. My main antenna is a Phased Array consisting of 2 full 今回はDxer 諸氏の間で定評のあるループアンテナWellbrook ALA1530 を前回のRF Systems EMF と比較してみた。. ALA1530 は英国Wellbrook 社の製 品であり、直径1mほどのアルミ製のループアンテナである。. 既に何人かのDxer の方がレ ビューを発表しておられるが、総括する The Wellbrook is powered over the feedline with a 12VDC bias-T injector. So you need a clean source of 12 volts. I use a cheap Talent Cell battery pack (available on Amazon in various capacities). These actually deliver 11.1 VDC (3x 3.7V), rather than the 12V the Wellbrook calls for, but it works fine in practice. I can also use the same pack |bjp| zkf| jix| gnx| bxh| jjn| pxx| gdq| jkc| hds| gid| lvq| oad| ugy| owk| aax| sul| mtn| ace| lyz| jpb| rvl| kef| wox| lie| arp| bow| asv| hnx| tuj| xgp| zzx| ekr| yxc| ofq| men| gzu| ymt| wou| fbk| mwr| hws| gvx| tpe| fbg| wzu| shx| uno| swh| ksm|
